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.

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.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input 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"
    }
}

For more information, see Reading Data from Amazon Kinesis Data Streams in the Amazon Kinesis Data Streams Developer Guide.

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.
