def change_resource_record_sets(HostedZoneId=None, ChangeBatch=None):
    """
    Creates, changes, or deletes a resource record set, which contains authoritative DNS information for a specified domain name or subdomain name. For example, you can use ChangeResourceRecordSets to create a resource record set that routes traffic for test.example.com to a web server that has an IP address of 192.0.2.44.
    The request body must include a document with a ChangeResourceRecordSetsRequest element. The request body contains a list of change items, known as a change batch. Change batches are considered transactional changes. When using the Amazon Route 53 API to change resource record sets, Amazon Route 53 either makes all or none of the changes in a change batch request. This ensures that Amazon Route 53 never partially implements the intended changes to the resource record sets in a hosted zone.
    For example, a change batch request that deletes the CNAME record for www.example.com and creates an alias resource record set for www.example.com. Amazon Route 53 deletes the first resource record set and creates the second resource record set in a single operation. If either the DELETE or the CREATE action fails, then both changes (plus any other changes in the batch) fail, and the original CNAME record continues to exist.
    To create resource record sets for complex routing configurations, use either the traffic flow visual editor in the Amazon Route 53 console or the API actions for traffic policies and traffic policy instances. Save the configuration as a traffic policy, then associate the traffic policy with one or more domain names (such as example.com) or subdomain names (such as www.example.com), in the same hosted zone or in multiple hosted zones. You can roll back the updates if the new configuration isn't performing as expected. For more information, see Using Traffic Flow to Route DNS Traffic in the Amazon Route 53 Developer Guide .
    Use ChangeResourceRecordsSetsRequest to perform the following actions:
    The syntax for a request depends on the type of resource record set that you want to create, delete, or update, such as weighted, alias, or failover. The XML elements in your request must appear in the order listed in the syntax.
    For an example for each type of resource record set, see "Examples."
    Don't refer to the syntax in the "Parameter Syntax" section, which includes all of the elements for every kind of resource record set that you can create, delete, or update by using ChangeResourceRecordSets .
    When you submit a ChangeResourceRecordSets request, Amazon Route 53 propagates your changes to all of the Amazon Route 53 authoritative DNS servers. While your changes are propagating, GetChange returns a status of PENDING . When propagation is complete, GetChange returns a status of INSYNC . Changes generally propagate to all Amazon Route 53 name servers in a few minutes. In rare circumstances, propagation can take up to 30 minutes. For more information, see  GetChange .
    For information about the limits on a ChangeResourceRecordSets request, see Limits in the Amazon Route 53 Developer Guide .

    :type HostedZoneId: string
    :param HostedZoneId: [REQUIRED]
            The ID of the hosted zone that contains the resource record sets that you want to change.
            

    :type ChangeBatch: dict
    :param ChangeBatch: [REQUIRED]
            A complex type that contains an optional comment and the Changes element.
            Comment (string) --
            Optional: Any comments you want to include about a change batch request.
            Changes (list) -- [REQUIRED]Information about the changes to make to the record sets.
            (dict) --The information for each resource record set that you want to change.
            Action (string) -- [REQUIRED]The action to perform:
            CREATE : Creates a resource record set that has the specified values.
            DELETE : Deletes a existing resource record set.
            Warning
            To delete the resource record set that is associated with a traffic policy instance, use `` DeleteTrafficPolicyInstance `` . Amazon Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Amazon Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.
            UPSERT : If a resource record set doesn't already exist, Amazon Route 53 creates it. If a resource record set does exist, Amazon Route 53 updates it with the values in the request.
            The values that you need to include in the request depend on the type of resource record set that you're creating, deleting, or updating:
            Basic resource record sets (excluding alias, failover, geolocation, latency, and weighted resource record sets)
            Name
            Type
            TTL
            Failover, geolocation, latency, or weighted resource record sets (excluding alias resource record sets)
            Name
            Type
            TTL
            SetIdentifier
            Alias resource record sets (including failover alias, geolocation alias, latency alias, and weighted alias resource record sets)
            Name
            Type
            AliasTarget (includes DNSName , EvaluateTargetHealth , and HostedZoneId )
            SetIdentifier (for failover, geolocation, latency, and weighted resource record sets)
            ResourceRecordSet (dict) -- [REQUIRED]Information about the resource record set to create, delete, or update.
            Name (string) -- [REQUIRED]The name of the domain you want to perform the action on.
            Enter a fully qualified domain name, for example, www.example.com . You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 still assumes that the domain name that you specify is fully qualified. This means that Amazon Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
            For information about how to specify characters other than a-z , 0-9 , and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide .
            You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com . Note the following:
            The * must replace the entire label. For example, you can't specify *prod.example.com or prod*.example.com .
            The * can't replace any of the middle labels, for example, marketing.*.example.com.
            If you include * in any position other than the leftmost label in a domain name, DNS treats it as an * character (ASCII 42), not as a wildcard.
            Warning
            You can't use the * wildcard for resource records sets that have a type of NS.
            You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com . You can't use an * for one of the middle labels, for example, marketing.*.example.com . In addition, the * must replace the entire label; for example, you can't specify prod*.example.com .
            Type (string) -- [REQUIRED]The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
            Valid values for basic resource record sets: A | AAAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
            Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT . When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
            Note
            SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value of Type is SPF . RFC 7208, Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1 , has been updated to say, '...[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it.' In RFC 7208, see section 14.1, The SPF DNS Record Type .
            Values for alias resource record sets:
            CloudFront distributions: A  If IPv6 is enabled for the distribution, create two resource record sets to route traffic to your distribution, one with a value of A and one with a value of AAAA .
            AWS Elastic Beanstalk environment that has a regionalized subdomain : A
            ELB load balancers: A | AAAA
            Amazon S3 buckets: A
            Another resource record set in this hosted zone: Specify the type of the resource record set for which you're creating the alias. Specify any value except NS or SOA .
            SetIdentifier (string) --
            Weighted, Latency, Geo, and Failover resource record sets only: An identifier that differentiates among multiple resource record sets that have the same combination of DNS name and type. The value of SetIdentifier must be unique for each resource record set that has the same combination of DNS name and type. Omit SetIdentifier for any other types of record sets.
            Weight (integer) --
            Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Amazon Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Amazon Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
            You must specify a value for the Weight element for every weighted resource record set.
            You can only specify one ResourceRecord per weighted resource record set.
            You can't create latency, failover, or geolocation resource record sets that have the same values for the Name and Type elements as weighted resource record sets.
            You can create a maximum of 100 weighted resource record sets that have the same values for the Name and Type elements.
            For weighted (but not weighted alias) resource record sets, if you set Weight to 0 for a resource record set, Amazon Route 53 never responds to queries with the applicable value for that resource record set. However, if you set Weight to 0 for all resource record sets that have the same combination of DNS name and type, traffic is routed to all resources with equal probability. The effect of setting Weight to 0 is different when you associate health checks with weighted resource record sets. For more information, see Options for Configuring Amazon Route 53 Active-Active and Active-Passive Failover in the Amazon Route 53 Developer Guide .
            Region (string) --
            Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
            Note
            Creating latency and latency alias resource record sets in private hosted zones is not supported.
            When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Amazon Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Amazon Route 53 then returns the value that is associated with the selected resource record set.
            Note the following:
            You can only specify one ResourceRecord per latency resource record set.
            You can only create one latency resource record set for each Amazon EC2 Region.
            You aren't required to create latency resource record sets for all Amazon EC2 Regions. Amazon Route 53 will choose the region with the best latency from among the regions that you create latency resource record sets for.
            You can't create non-latency resource record sets that have the same values for the Name and Type elements as latency resource record sets.
            GeoLocation (dict) --
            Geo location resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111 , create a resource record set with a Type of A and a ContinentCode of AF .
            Note
            Creating geolocation and geolocation alias resource record sets in private hosted zones is not supported.
            If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
            You can't create two geolocation resource record sets that specify the same geographic location.
            The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
            Warning
            Geolocation works by mapping IP addresses to locations. However, some IP addresses aren't mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Amazon Route 53 will receive some DNS queries from locations that it can't identify. We recommend that you create a resource record set for which the value of CountryCode is * , which handles both queries that come from locations for which you haven't created geolocation resource record sets and queries from IP addresses that aren't mapped to a location. If you don't create a * resource record set, Amazon Route 53 returns a 'no answer' response for queries from those locations.
            You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
            ContinentCode (string) --The two-letter code for the continent.
            Valid values: AF | AN | AS | EU | OC | NA | SA
            Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
            CountryCode (string) --The two-letter code for the country.
            SubdivisionCode (string) --The code for the subdivision, for example, a state in the United States or a province in Canada.
            Failover (string) --
            Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover ; for the other resource record set, you specify SECONDARY . In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
            Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
            When the primary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the secondary resource record set.
            When the primary resource record set is unhealthy and the secondary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the secondary resource record set.
            When the secondary resource record set is unhealthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the primary resource record set.
            If you omit the HealthCheckId element for the secondary resource record set, and if the primary resource record set is unhealthy, Amazon Route 53 always responds to DNS queries with the applicable value from the secondary resource record set. This is true regardless of the health of the associated endpoint.
            You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
            For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
            For more information about configuring failover for Amazon Route 53, see the following topics in the Amazon Route 53 Developer Guide :
            Amazon Route 53 Health Checks and DNS Failover
            Configuring Failover in a Private Hosted Zone
            TTL (integer) --The resource record cache time to live (TTL), in seconds. Note the following:
            If you're creating an alias resource record set, omit TTL . Amazon Route 53 uses the value of TTL for the alias target.
            If you're associating this resource record set with a health check (if you're adding a HealthCheckId element), we recommend that you specify a TTL of 60 seconds or less so clients respond quickly to changes in health status.
            All of the resource record sets in a group of weighted resource record sets must have the same value for TTL .
            If a group of weighted resource record sets includes one or more weighted alias resource record sets for which the alias target is an ELB load balancer, we recommend that you specify a TTL of 60 seconds for all of the non-alias weighted resource record sets that have the same name and type. Values other than 60 seconds (the TTL for load balancers) will change the effect of the values that you specify for Weight .
            ResourceRecords (list) --Information about the resource records to act upon.
            Note
            If you're creating an alias resource record set, omit ResourceRecords .
            (dict) --Information specific to the resource record.
            Note
            If you're creating an alias resource record set, omit ResourceRecord .
            Value (string) -- [REQUIRED]The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
            You can specify more than one value for all record types except CNAME and SOA .
            Note
            If you're creating an alias resource record set, omit Value .
            
            AliasTarget (dict) --
            Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
            If you're creating resource records sets for a private hosted zone, note the following:
            You can't create alias resource record sets for CloudFront distributions in a private hosted zone.
            Creating geolocation alias resource record sets or latency alias resource record sets in a private hosted zone is unsupported.
            For information about creating failover resource record sets in a private hosted zone, see Configuring Failover in a Private Hosted Zone in the Amazon Route 53 Developer Guide .
            HostedZoneId (string) -- [REQUIRED]
            Alias resource records sets only : The value used depends on where you want to route traffic:
            CloudFront distribution
            Specify Z2FDTNDATAQYW2 .
            Note
            Alias resource record sets for CloudFront can't be created in a private zone.
            Elastic Beanstalk environment
            Specify the hosted zone ID for the region in which you created the environment. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the 'AWS Regions and Endpoints' chapter of the Amazon Web Services General Reference .
            ELB load balancer
            Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
            Elastic Load Balancing table in the 'AWS Regions and Endpoints' chapter of the Amazon Web Services General Reference : Use the value in the 'Amazon Route 53 Hosted Zone ID' column that corresponds with the region that you created your load balancer in.
            AWS Management Console : Go to the Amazon EC2 page, click Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab.
            Elastic Load Balancing API : Use DescribeLoadBalancers to get the value of CanonicalHostedZoneNameId . For more information, see the applicable guide:
            Classic Load Balancer: DescribeLoadBalancers
            Application Load Balancer: DescribeLoadBalancers
            AWS CLI : Use `` describe-load-balancers `` to get the value of CanonicalHostedZoneNameID .An Amazon S3 bucket configured as a static website
            Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the 'AWS Regions and Endpoints' chapter of the Amazon Web Services General Reference .
            Another Amazon Route 53 resource record set in your hosted zone
            Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
            DNSName (string) -- [REQUIRED]
            Alias resource record sets only: The value that you specify depends on where you want to route queries:
            CloudFront distribution
            Specify the domain name that CloudFront assigned when you created your distribution.
            Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide .
            Elastic Beanstalk environment
            Specify the CNAME attribute for the environment. (The environment must have a regionalized domain name.) You can use the following methods to get the value of the CNAME attribute:
            AWS Management Console : For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide .
            Elastic Beanstalk API : Use the DescribeEnvironments action to get the value of the CNAME attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference .
            AWS CLI : Use the describe-environments command to get the value of the CNAME attribute. For more information, see describe-environments in the AWS Command Line Interface Reference .ELB load balancer
            Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
            AWS Management Console : Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. (If you're routing traffic to a Classic Load Balancer, get the value that begins with dualstack .)
            Elastic Load Balancing API : Use DescribeLoadBalancers to get the value of DNSName . For more information, see the applicable guide:
            Classic Load Balancer: DescribeLoadBalancers
            Application Load Balancer: DescribeLoadBalancers
            AWS CLI : Use `` describe-load-balancers `` to get the value of DNSName .Amazon S3 bucket that is configured as a static website
            Specify the domain name of the Amazon S3 website endpoint in which you created the bucket, for example, s3-website-us-east-2.amazonaws.com . For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference . For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
            Another Amazon Route 53 resource record set
            Specify the value of the Name element for a resource record set in the current hosted zone.
            EvaluateTargetHealth (boolean) -- [REQUIRED]
            Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true , an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer, or the referenced resource record set.
            Note the following:
            You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
            If the AWS resource that you specify in AliasTarget is a resource record set or a group of resource record sets (for example, a group of weighted resource record sets), but it is not another alias resource record set, we recommend that you associate a health check with all of the resource record sets in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide .
            If you specify an Elastic Beanstalk environment in HostedZoneId and DNSName , and if the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one EC2 instance.) If you set EvaluateTargetHealth to true and either no EC2 instances are healthy or the load balancer itself is unhealthy, Amazon Route 53 routes queries to other available resources that are healthy, if any. If the environment contains a single EC2 instance, there are no special requirements.
            If you specify an ELB load balancer in `` AliasTarget `` , ELB routes queries only to the healthy EC2 instances that are registered with the load balancer. If no EC2 instances are healthy or if the load balancer itself is unhealthy, and if EvaluateTargetHealth is true for the corresponding alias resource record set, Amazon Route 53 routes queries to other resources. When you create a load balancer, you configure settings for ELB health checks; they're not Amazon Route 53 health checks, but they perform a similar function. Do not create Amazon Route 53 health checks for the EC2 instances that you register with an ELB load balancer. For more information, see How Health Checks Work in More Complex Amazon Route 53 Configurations in the Amazon Route 53 Developer Guide .
            We recommend that you set EvaluateTargetHealth to true only when you have enough idle capacity to handle the failure of one or more endpoints.
            For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide .
            HealthCheckId (string) --If you want Amazon Route 53 to return this resource record set in response to a DNS query only when a health check is passing, include the HealthCheckId element and specify the ID of the applicable health check.
            Amazon Route 53 determines whether a resource record set is healthy based on one of the following:
            By periodically sending a request to the endpoint that is specified in the health check
            By aggregating the status of a specified group of health checks (calculated health checks)
            By determining the current state of a CloudWatch alarm (CloudWatch metric health checks)
            For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy .
            The HealthCheckId element is only useful when Amazon Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Amazon Route 53 to base the choice in part on the status of a health check. Configuring health checks only makes sense in the following configurations:
            You're checking the health of the resource record sets in a group of weighted, latency, geolocation, or failover resource record sets, and you specify health check IDs for all of the resource record sets. If the health check for one resource record set specifies an endpoint that is not healthy, Amazon Route 53 stops responding to queries using the value for that resource record set.
            You set EvaluateTargetHealth to true for the resource record sets in a group of alias, weighted alias, latency alias, geolocation alias, or failover alias resource record sets, and you specify health check IDs for all of the resource record sets that are referenced by the alias resource record sets.
            Warning
            Amazon Route 53 doesn't check the health of the endpoint specified in the resource record set, for example, the endpoint specified by the IP address in the Value element. When you add a HealthCheckId element to a resource record set, Amazon Route 53 checks the health of the endpoint that you specified in the health check.
            For geolocation resource record sets, if an endpoint is unhealthy, Amazon Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the United States, for North America, and for all locations. If the endpoint for the state resource record set is unhealthy, Amazon Route 53 checks the resource record sets for the United States, for North America, and for all locations (a resource record set for which the value of CountryCode is * ), in that order, until it finds a resource record set for which the endpoint is healthy.
            If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com . For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com ), not the name of the resource record sets (example.com).
            Warning
            n this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and then associate the health check with those resource record sets, health check results will be unpredictable.
            For more information, see the following topics in the Amazon Route 53 Developer Guide :

            Configuring Failover in a Private Hosted Zone
            TrafficPolicyInstanceId (string) --When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Amazon Route 53 created this resource record set for.
            Warning
            To delete the resource record set that is associated with a traffic policy instance, use DeleteTrafficPolicyInstance . Amazon Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Amazon Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.

    A complex type that contains an optional comment and the Changes element.
    
    Comment (string) --
    Optional: Any comments you want to include about a change batch request.
    
    Changes (list) -- [REQUIRED]Information about the changes to make to the record sets.
    
    (dict) --The information for each resource record set that you want to change.
    
    Action (string) -- [REQUIRED]The action to perform:
    
    CREATE : Creates a resource record set that has the specified values.
    DELETE : Deletes a existing resource record set.
    
    
    Warning
    To delete the resource record set that is associated with a traffic policy instance, use ``  DeleteTrafficPolicyInstance `` . Amazon Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Amazon Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.
    
    
    UPSERT : If a resource record set doesn't already exist, Amazon Route 53 creates it. If a resource record set does exist, Amazon Route 53 updates it with the values in the request.
    
    The values that you need to include in the request depend on the type of resource record set that you're creating, deleting, or updating:
    
    Basic resource record sets (excluding alias, failover, geolocation, latency, and weighted resource record sets)
    
    Name
    Type
    TTL
    
    
    Failover, geolocation, latency, or weighted resource record sets (excluding alias resource record sets)
    
    Name
    Type
    TTL
    SetIdentifier
    
    
    Alias resource record sets (including failover alias, geolocation alias, latency alias, and weighted alias resource record sets)
    
    Name
    Type
    AliasTarget (includes DNSName , EvaluateTargetHealth , and HostedZoneId )
    SetIdentifier (for failover, geolocation, latency, and weighted resource record sets)
    
    
    ResourceRecordSet (dict) -- [REQUIRED]Information about the resource record set to create, delete, or update.
    
    Name (string) -- [REQUIRED]The name of the domain you want to perform the action on.
    Enter a fully qualified domain name, for example, www.example.com . You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 still assumes that the domain name that you specify is fully qualified. This means that Amazon Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
    For information about how to specify characters other than a-z , 0-9 , and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide .
    You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com . Note the following:
    
    The * must replace the entire label. For example, you can't specify *prod.example.com or prod*.example.com .
    The * can't replace any of the middle labels, for example, marketing.*.example.com.
    If you include * in any position other than the leftmost label in a domain name, DNS treats it as an * character (ASCII 42), not as a wildcard.
    
    
    Warning
    You can't use the * wildcard for resource records sets that have a type of NS.
    
    You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com . You can't use an * for one of the middle labels, for example, marketing.*.example.com . In addition, the * must replace the entire label; for example, you can't specify prod*.example.com .
    
    Type (string) -- [REQUIRED]The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
    Valid values for basic resource record sets: A | AAAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
    Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT . When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
    
    Note
    SPF records were formerly used to verify the identity of the sender of email messages. However, we no longer recommend that you create resource record sets for which the value of Type is SPF . RFC 7208, Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1 , has been updated to say, "...[I]ts existence and mechanism defined in [RFC4408] have led to some interoperability issues. Accordingly, its use is no longer appropriate for SPF version 1; implementations are not to use it." In RFC 7208, see section 14.1, The SPF DNS Record Type .
    
    Values for alias resource record sets:
    
    CloudFront distributions: A   If IPv6 is enabled for the distribution, create two resource record sets to route traffic to your distribution, one with a value of A and one with a value of AAAA .
    AWS Elastic Beanstalk environment that has a regionalized subdomain : A
    ELB load balancers: A | AAAA
    Amazon S3 buckets: A
    Another resource record set in this hosted zone: Specify the type of the resource record set for which you're creating the alias. Specify any value except NS or SOA .
    
    
    SetIdentifier (string) --
    Weighted, Latency, Geo, and Failover resource record sets only: An identifier that differentiates among multiple resource record sets that have the same combination of DNS name and type. The value of SetIdentifier must be unique for each resource record set that has the same combination of DNS name and type. Omit SetIdentifier for any other types of record sets.
    
    Weight (integer) --
    Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Amazon Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Amazon Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
    
    You must specify a value for the Weight element for every weighted resource record set.
    You can only specify one ResourceRecord per weighted resource record set.
    You can't create latency, failover, or geolocation resource record sets that have the same values for the Name and Type elements as weighted resource record sets.
    You can create a maximum of 100 weighted resource record sets that have the same values for the Name and Type elements.
    For weighted (but not weighted alias) resource record sets, if you set Weight to 0 for a resource record set, Amazon Route 53 never responds to queries with the applicable value for that resource record set. However, if you set Weight to 0 for all resource record sets that have the same combination of DNS name and type, traffic is routed to all resources with equal probability. The effect of setting Weight to 0 is different when you associate health checks with weighted resource record sets. For more information, see Options for Configuring Amazon Route 53 Active-Active and Active-Passive Failover in the Amazon Route 53 Developer Guide .
    
    
    Region (string) --
    Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
    
    Note
    Creating latency and latency alias resource record sets in private hosted zones is not supported.
    
    When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Amazon Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Amazon Route 53 then returns the value that is associated with the selected resource record set.
    Note the following:
    
    You can only specify one ResourceRecord per latency resource record set.
    You can only create one latency resource record set for each Amazon EC2 Region.
    You aren't required to create latency resource record sets for all Amazon EC2 Regions. Amazon Route 53 will choose the region with the best latency from among the regions that you create latency resource record sets for.
    You can't create non-latency resource record sets that have the same values for the Name and Type elements as latency resource record sets.
    
    
    GeoLocation (dict) --
    Geo location resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111 , create a resource record set with a Type of A and a ContinentCode of AF .
    
    Note
    Creating geolocation and geolocation alias resource record sets in private hosted zones is not supported.
    
    If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
    You can't create two geolocation resource record sets that specify the same geographic location.
    The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
    
    Warning
    Geolocation works by mapping IP addresses to locations. However, some IP addresses aren't mapped to geographic locations, so even if you create geolocation resource record sets that cover all seven continents, Amazon Route 53 will receive some DNS queries from locations that it can't identify. We recommend that you create a resource record set for which the value of CountryCode is * , which handles both queries that come from locations for which you haven't created geolocation resource record sets and queries from IP addresses that aren't mapped to a location. If you don't create a * resource record set, Amazon Route 53 returns a "no answer" response for queries from those locations.
    
    You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
    
    ContinentCode (string) --The two-letter code for the continent.
    Valid values: AF | AN | AS | EU | OC | NA | SA
    Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
    
    CountryCode (string) --The two-letter code for the country.
    
    SubdivisionCode (string) --The code for the subdivision, for example, a state in the United States or a province in Canada.
    
    
    
    Failover (string) --
    Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover ; for the other resource record set, you specify SECONDARY . In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
    Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
    
    When the primary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the secondary resource record set.
    When the primary resource record set is unhealthy and the secondary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the secondary resource record set.
    When the secondary resource record set is unhealthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the primary resource record set.
    If you omit the HealthCheckId element for the secondary resource record set, and if the primary resource record set is unhealthy, Amazon Route 53 always responds to DNS queries with the applicable value from the secondary resource record set. This is true regardless of the health of the associated endpoint.
    
    You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
    For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
    For more information about configuring failover for Amazon Route 53, see the following topics in the Amazon Route 53 Developer Guide :
    
    Amazon Route 53 Health Checks and DNS Failover
    Configuring Failover in a Private Hosted Zone
    
    
    TTL (integer) --The resource record cache time to live (TTL), in seconds. Note the following:
    
    If you're creating an alias resource record set, omit TTL . Amazon Route 53 uses the value of TTL for the alias target.
    If you're associating this resource record set with a health check (if you're adding a HealthCheckId element), we recommend that you specify a TTL of 60 seconds or less so clients respond quickly to changes in health status.
    All of the resource record sets in a group of weighted resource record sets must have the same value for TTL .
    If a group of weighted resource record sets includes one or more weighted alias resource record sets for which the alias target is an ELB load balancer, we recommend that you specify a TTL of 60 seconds for all of the non-alias weighted resource record sets that have the same name and type. Values other than 60 seconds (the TTL for load balancers) will change the effect of the values that you specify for Weight .
    
    
    ResourceRecords (list) --Information about the resource records to act upon.
    
    Note
    If you're creating an alias resource record set, omit ResourceRecords .
    
    
    (dict) --Information specific to the resource record.
    
    Note
    If you're creating an alias resource record set, omit ResourceRecord .
    
    
    Value (string) -- [REQUIRED]The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide .
    You can specify more than one value for all record types except CNAME and SOA .
    
    Note
    If you're creating an alias resource record set, omit Value .
    
    
    
    
    
    
    AliasTarget (dict) --
    Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
    If you're creating resource records sets for a private hosted zone, note the following:
    
    You can't create alias resource record sets for CloudFront distributions in a private hosted zone.
    Creating geolocation alias resource record sets or latency alias resource record sets in a private hosted zone is unsupported.
    For information about creating failover resource record sets in a private hosted zone, see Configuring Failover in a Private Hosted Zone in the Amazon Route 53 Developer Guide .
    
    
    HostedZoneId (string) -- [REQUIRED]
    Alias resource records sets only : The value used depends on where you want to route traffic:
    CloudFront distribution
    
    Specify Z2FDTNDATAQYW2 .
    
    Note
    Alias resource record sets for CloudFront can't be created in a private zone.
    Elastic Beanstalk environment
    
    Specify the hosted zone ID for the region in which you created the environment. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
    
    ELB load balancer
    Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
    
    Elastic Load Balancing table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference : Use the value in the "Amazon Route 53 Hosted Zone ID" column that corresponds with the region that you created your load balancer in.
    AWS Management Console : Go to the Amazon EC2 page, click Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab.
    Elastic Load Balancing API : Use DescribeLoadBalancers to get the value of CanonicalHostedZoneNameId . For more information, see the applicable guide:
    Classic Load Balancer: DescribeLoadBalancers
    Application Load Balancer: DescribeLoadBalancers
    
    
    AWS CLI : Use `` describe-load-balancers `` to get the value of CanonicalHostedZoneNameID .An Amazon S3 bucket configured as a static website
    
    
    Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference .
    
    Another Amazon Route 53 resource record set in your hosted zone
    Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
    
    DNSName (string) -- [REQUIRED]
    Alias resource record sets only: The value that you specify depends on where you want to route queries:
    CloudFront distribution
    
    Specify the domain name that CloudFront assigned when you created your distribution.
    Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com , your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide .
    
    Elastic Beanstalk environment
    Specify the CNAME attribute for the environment. (The environment must have a regionalized domain name.) You can use the following methods to get the value of the CNAME attribute:
    
    AWS Management Console : For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide .
    Elastic Beanstalk API : Use the DescribeEnvironments action to get the value of the CNAME attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference .
    AWS CLI : Use the describe-environments command to get the value of the CNAME attribute. For more information, see describe-environments in the AWS Command Line Interface Reference .ELB load balancer
    
    
    Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
    
    AWS Management Console : Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. (If you're routing traffic to a Classic Load Balancer, get the value that begins with dualstack .)
    Elastic Load Balancing API : Use DescribeLoadBalancers to get the value of DNSName . For more information, see the applicable guide:
    Classic Load Balancer: DescribeLoadBalancers
    Application Load Balancer: DescribeLoadBalancers
    
    
    AWS CLI : Use `` describe-load-balancers `` to get the value of DNSName .Amazon S3 bucket that is configured as a static website
    
    
    Specify the domain name of the Amazon S3 website endpoint in which you created the bucket, for example, s3-website-us-east-2.amazonaws.com . For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference . For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
    
    Another Amazon Route 53 resource record set
    Specify the value of the Name element for a resource record set in the current hosted zone.
    
    EvaluateTargetHealth (boolean) -- [REQUIRED]
    Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true , an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer, or the referenced resource record set.
    Note the following:
    
    You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
    If the AWS resource that you specify in AliasTarget is a resource record set or a group of resource record sets (for example, a group of weighted resource record sets), but it is not another alias resource record set, we recommend that you associate a health check with all of the resource record sets in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide .
    If you specify an Elastic Beanstalk environment in HostedZoneId and DNSName , and if the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one EC2 instance.) If you set EvaluateTargetHealth to true and either no EC2 instances are healthy or the load balancer itself is unhealthy, Amazon Route 53 routes queries to other available resources that are healthy, if any. If the environment contains a single EC2 instance, there are no special requirements.
    If you specify an ELB load balancer in ``  AliasTarget `` , ELB routes queries only to the healthy EC2 instances that are registered with the load balancer. If no EC2 instances are healthy or if the load balancer itself is unhealthy, and if EvaluateTargetHealth is true for the corresponding alias resource record set, Amazon Route 53 routes queries to other resources. When you create a load balancer, you configure settings for ELB health checks; they're not Amazon Route 53 health checks, but they perform a similar function. Do not create Amazon Route 53 health checks for the EC2 instances that you register with an ELB load balancer. For more information, see How Health Checks Work in More Complex Amazon Route 53 Configurations in the Amazon Route 53 Developer Guide .
    We recommend that you set EvaluateTargetHealth to true only when you have enough idle capacity to handle the failure of one or more endpoints.
    
    For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide .
    
    
    
    HealthCheckId (string) --If you want Amazon Route 53 to return this resource record set in response to a DNS query only when a health check is passing, include the HealthCheckId element and specify the ID of the applicable health check.
    Amazon Route 53 determines whether a resource record set is healthy based on one of the following:
    
    By periodically sending a request to the endpoint that is specified in the health check
    By aggregating the status of a specified group of health checks (calculated health checks)
    By determining the current state of a CloudWatch alarm (CloudWatch metric health checks)
    
    For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy .
    The HealthCheckId element is only useful when Amazon Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Amazon Route 53 to base the choice in part on the status of a health check. Configuring health checks only makes sense in the following configurations:
    
    You're checking the health of the resource record sets in a group of weighted, latency, geolocation, or failover resource record sets, and you specify health check IDs for all of the resource record sets. If the health check for one resource record set specifies an endpoint that is not healthy, Amazon Route 53 stops responding to queries using the value for that resource record set.
    You set EvaluateTargetHealth to true for the resource record sets in a group of alias, weighted alias, latency alias, geolocation alias, or failover alias resource record sets, and you specify health check IDs for all of the resource record sets that are referenced by the alias resource record sets.
    
    
    Warning
    Amazon Route 53 doesn't check the health of the endpoint specified in the resource record set, for example, the endpoint specified by the IP address in the Value element. When you add a HealthCheckId element to a resource record set, Amazon Route 53 checks the health of the endpoint that you specified in the health check.
    
    For geolocation resource record sets, if an endpoint is unhealthy, Amazon Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the United States, for North America, and for all locations. If the endpoint for the state resource record set is unhealthy, Amazon Route 53 checks the resource record sets for the United States, for North America, and for all locations (a resource record set for which the value of CountryCode is * ), in that order, until it finds a resource record set for which the endpoint is healthy.
    If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com . For the value of FullyQualifiedDomainName , specify the domain name of the server (such as us-east-2-www.example.com ), not the name of the resource record sets (example.com).
    
    Warning
    n this configuration, if you create a health check for which the value of FullyQualifiedDomainName matches the name of the resource record sets and then associate the health check with those resource record sets, health check results will be unpredictable.

    TrafficPolicyInstanceId (string) --When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Amazon Route 53 created this resource record set for.
    
    Warning
    To delete the resource record set that is associated with a traffic policy instance, use DeleteTrafficPolicyInstance . Amazon Route 53 will delete the resource record set automatically. If you delete the resource record set by using ChangeResourceRecordSets , Amazon Route 53 doesn't automatically delete the traffic policy instance, and you'll continue to be charged for it even though it's no longer in use.
