def put_targets(Rule=None, Targets=None):
    """
    Adds the specified targets to the specified rule, or updates the targets if they are already associated with the rule.
    Targets are the resources that are invoked when a rule is triggered. Example targets include EC2 instances, AWS Lambda functions, Amazon Kinesis streams, Amazon ECS tasks, AWS Step Functions state machines, and built-in targets. Note that creating rules with built-in targets is supported only in the AWS Management Console.
    For some target types, PutTargets provides target-specific parameters. If the target is an Amazon Kinesis stream, you can optionally specify which shard the event goes to by using the KinesisParameters argument. To invoke a command on multiple EC2 instances with one rule, you can use the RunCommandParameters field.
    To be able to make API calls against the resources that you own, Amazon CloudWatch Events needs the appropriate permissions. For AWS Lambda and Amazon SNS resources, CloudWatch Events relies on resource-based policies. For EC2 instances, Amazon Kinesis streams, and AWS Step Functions state machines, CloudWatch Events relies on IAM roles that you specify in the RoleARN argument in PutTarget . For more information, see Authentication and Access Control in the Amazon CloudWatch Events User Guide .
    When you specify Input , InputPath , or InputTransformer , you must use JSON dot notation, not bracket notation.
    When you add targets to a rule and the associated rule triggers soon after, new or updated targets might not be immediately invoked. Please allow a short period of time for changes to take effect.
    This action can partially fail if too many requests are made at the same time. If that happens, FailedEntryCount is non-zero in the response and each entry in FailedEntries provides the ID of the failed target and the error code.
