def add_application_input(ApplicationName=None, CurrentApplicationVersionId
    =None, Input=None):
    """
    Adds a streaming source to your Amazon Kinesis application. For conceptual information, see Configuring Application Input .
    You can add a streaming source either when you create an application or you can use this operation to add a streaming source after you create an application. For more information, see  CreateApplication .
    Any configuration update, including adding a streaming source using this operation, results in a new version of the application. You can use the  DescribeApplication operation to find the current application version.
    This operation requires permissions to perform the kinesisanalytics:AddApplicationInput action.

    :type ApplicationName: string

            Name of your existing Amazon Kinesis Analytics application to which you want to add the streaming source.
            

    :type CurrentApplicationVersionId: integer
    :param CurrentApplicationVersionId: [REQUIRED]
            Current version of your Amazon Kinesis Analytics application. You can use the DescribeApplication operation to find the current application version.
            

    :type Input: dict
    :param Input: [REQUIRED]
            When you configure the application input, you specify the streaming source, the in-application stream name that is created, and the mapping between the two. For more information, see Configuring Application Input .
            NamePrefix (string) -- [REQUIRED]Name prefix to use when creating in-application stream. Suppose you specify a prefix 'MyInApplicationStream'. Kinesis Analytics will then create one or more (as per the InputParallelism count you specified) in-application streams with names 'MyInApplicationStream_001', 'MyInApplicationStream_002' and so on.
            KinesisStreamsInput (dict) --If the streaming source is an Amazon Kinesis stream, identifies the stream's Amazon Resource Name (ARN) and an IAM role that enables Amazon Kinesis Analytics to access the stream on your behalf.
            ResourceARN (string) -- [REQUIRED]ARN of the input Amazon Kinesis stream to read.
            RoleARN (string) -- [REQUIRED]ARN of the IAM role that Amazon Kinesis Analytics can assume to access the stream on your behalf. You need to grant the necessary permissions to this role.
            KinesisFirehoseInput (dict) --If the streaming source is an Amazon Kinesis Firehose delivery stream, identifies the Firehose delivery stream's ARN and an IAM role that enables Amazon Kinesis Analytics to access the stream on your behalf.
            ResourceARN (string) -- [REQUIRED]ARN of the input Firehose delivery stream.
            RoleARN (string) -- [REQUIRED]ARN of the IAM role that Amazon Kinesis Analytics can assume to access the stream on your behalf. You need to make sure the role has necessary permissions to access the stream.
            InputParallelism (dict) --Describes the number of in-application streams to create.
            Data from your source will be routed to these in-application input streams.
            (see Configuring Application Input .
            Count (integer) --Number of in-application streams to create. For more information, see Limits .
            InputSchema (dict) -- [REQUIRED]Describes the format of the data in the streaming source, and how each data element maps to corresponding columns in the in-application stream that is being created.
            Also used to describe the format of the reference data source.
            RecordFormat (dict) -- [REQUIRED]Specifies the format of the records on the streaming source.
            RecordFormatType (string) -- [REQUIRED]The type of record format.
            MappingParameters (dict) --When configuring application input at the time of creating or updating an application, provides additional mapping information specific to the record format (such as JSON, CSV, or record fields delimited by some delimiter) on the streaming source.
            JSONMappingParameters (dict) --Provides additional mapping information when JSON is the record format on the streaming source.
            RecordRowPath (string) -- [REQUIRED]Path to the top-level parent that contains the records.
            For example, consider the following JSON record:
            In the RecordRowPath , '$' refers to the root and path '$.vehicle.Model' refers to the specific 'Model' key in the JSON.
            CSVMappingParameters (dict) --Provides additional mapping information when the record format uses delimiters (for example, CSV).
            RecordRowDelimiter (string) -- [REQUIRED]Row delimiter. For example, in a CSV format, 'n' is the typical row delimiter.
            RecordColumnDelimiter (string) -- [REQUIRED]Column delimiter. For example, in a CSV format, a comma (',') is the typical column delimiter.
            
            RecordEncoding (string) --Specifies the encoding of the records in the streaming source. For example, UTF-8.
            RecordColumns (list) -- [REQUIRED]A list of RecordColumn objects.
            (dict) --Describes the mapping of each data element in the streaming source to the corresponding column in the in-application stream.
            Also used to describe the format of the reference data source.
            Name (string) -- [REQUIRED]Name of the column created in the in-application input stream or reference table.
            Mapping (string) --Reference to the data element in the streaming input of the reference data source.
            SqlType (string) -- [REQUIRED]Type of column created in the in-application input stream or reference table.
