describe-stream-consumer¶

Description¶

To get the description of a registered consumer, provide the ARN of the consumer. Alternatively, you can provide the ARN of the data stream and the name you gave the consumer when you registered it. You may also provide all three parameters, as long as they don’t conflict with each other. If you don’t know the name or ARN of the consumer that you want to describe, you can use the ListStreamConsumers operation to get a list of the descriptions of all the consumers that are currently registered with a given data stream.

This operation has a limit of 20 transactions per second per stream.

Synopsis¶

  describe-stream-consumer
[--stream-arn <value>]
[--consumer-name <value>]
[--consumer-arn <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--stream-arn (string)

The ARN of the Kinesis data stream that the consumer is registered with. For more information, see Amazon Resource Names (ARNs) and Amazon Web Services Service Namespaces .

--consumer-name (string)

The name that you gave to the consumer.

--consumer-arn (string)

The ARN returned by Kinesis Data Streams when you registered the consumer.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe a data stream consumer

The following describe-stream-consumer example returns the description of the specified consumer, registered with the specified data stream.

aws kinesis describe-stream-consumer \
    --stream-arn arn:aws:kinesis:us-west-2:012345678912:stream/samplestream \
    --consumer-name KinesisConsumerApplication

Output:

{
    "ConsumerDescription": {
        "ConsumerName": "KinesisConsumerApplication",
        "ConsumerARN": "arn:aws:kinesis:us-west-2:123456789012:stream/samplestream/consumer/KinesisConsumerApplication:1572383852",
        "ConsumerStatus": "ACTIVE",
        "ConsumerCreationTimestamp": 1572383852.0,
        "StreamARN": "arn:aws:kinesis:us-west-2:123456789012:stream/samplestream"
    }
}

Output¶

ConsumerDescription -> (structure)

An object that represents the details of the consumer.

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)

StreamARN -> (string)

The ARN of the stream with which you registered the consumer.
