register_stream_consumer

Kinesis.Client.register_stream_consumer(**kwargs)

Registers a consumer with a Kinesis data stream. When you use this operation, the consumer you register can then call SubscribeToShard to receive data from the stream using enhanced fan-out, at a rate of up to 2 MiB per second for every shard you subscribe to. This rate is unaffected by the total number of consumers that read from the same stream.

You can register up to 20 consumers per stream. A given consumer can only be registered with one stream at a time.

For an example of how to use this operations, see Enhanced Fan-Out Using the Kinesis Data Streams API.

The use of this operation has a limit of five transactions per second per account. Also, only 5 consumers can be created simultaneously. In other words, you cannot have more than 5 consumers in a CREATING status at the same time. Registering a 6th consumer while there are 5 in a CREATING status results in a LimitExceededException .

Request Syntax

response = client.register_stream_consumer(
    StreamARN='string',
    ConsumerName='string'
)

Parameters

• StreamARN (string) --

  [REQUIRED]

  The ARN of the Kinesis data stream that you want to register the consumer with. For more info, see Amazon Resource Names (ARNs) and Amazon Web Services Service Namespaces.

• ConsumerName (string) --

  [REQUIRED]

  For a given Kinesis data stream, each consumer must have a unique name. However, consumer names don't have to be unique across data streams.

Return type

dict

Returns

Response Syntax

{
    'Consumer': {
        'ConsumerName': 'string',
        'ConsumerARN': 'string',
        'ConsumerStatus': 'CREATING'|'DELETING'|'ACTIVE',
        'ConsumerCreationTimestamp': datetime(2015, 1, 1)
    }
}

Response Structure

• (dict) --

  • Consumer (dict) --

    An object that represents the details of the consumer you registered. When you register a consumer, it gets an ARN that is generated by Kinesis Data Streams.

    • ConsumerName (string) --

      The name of the consumer is something you choose when you register the consumer.

    • ConsumerARN (string) --

      When you register a consumer, Kinesis Data Streams generates an ARN for it. You need this ARN to be able to call SubscribeToShard.

      If you delete a consumer and then create a new one with the same name, it won't have the same ARN. That's because consumer ARNs contain the creation timestamp. This is important to keep in mind if you have IAM policies that reference consumer ARNs.

    • ConsumerStatus (string) --

      A consumer can't read data while in the CREATING or DELETING states.

    • ConsumerCreationTimestamp (datetime) --

Exceptions

• Kinesis.Client.exceptions.InvalidArgumentException
• Kinesis.Client.exceptions.LimitExceededException
• Kinesis.Client.exceptions.ResourceInUseException
• Kinesis.Client.exceptions.ResourceNotFoundException
