list-stream-consumers

Description

Lists the consumers registered to receive data from a stream using enhanced fan-out, and provides information about each consumer.

This operation has a limit of 10 transactions per second per account.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

list-stream-consumers is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Consumers

Synopsis

  list-stream-consumers
--stream-arn <value>
[--stream-creation-timestamp <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--stream-arn (string)

The ARN of the Kinesis data stream for which you want to list the registered consumers. For more information, see Amazon Resource Names (ARNs) and AWS Service Namespaces .

--stream-creation-timestamp (timestamp)

Specify this input parameter to distinguish data streams that have the same name. For example, if you create a data stream and then delete it, and you later create another data stream with the same name, you can use this input parameter to specify which of the two streams you want to list the consumers for.

You can't specify this parameter if you specify the NextToken parameter.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

Consumers -> (list)

An array of JSON objects. Each object represents one registered consumer.

(structure)

An object that represents the details of the consumer you registered.

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 -> (timestamp)

NextToken -> (string)

When the number of consumers that are registered with the data stream is greater than the default value for the MaxResults parameter, or if you explicitly specify a value for MaxResults that is less than the number of registered consumers, the response includes a pagination token named NextToken . You can specify this NextToken value in a subsequent call to ListStreamConsumers to list the next set of registered consumers. For more information about the use of this pagination token when calling the ListStreamConsumers operation, see ListStreamConsumersInput$NextToken .

Warning

Tokens expire after 300 seconds. When you obtain a value for NextToken in the response to a call to ListStreamConsumers , you have 300 seconds to use that value. If you specify an expired token in a call to ListStreamConsumers , you get ExpiredNextTokenException .
