[ aws . dynamodbstreams ]

list-streams

Description

Returns an array of stream ARNs associated with the current account and endpoint. If the TableName parameter is present, then ListStreams will return only the streams ARNs for that table.

Note

You can call ListStreams at a maximum rate of 5 times per second.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  list-streams
[--table-name <value>]
[--limit <value>]
[--exclusive-start-stream-arn <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--table-name (string)

If this parameter is provided, then only the streams associated with this table name are returned.

--limit (integer)

The maximum number of streams to return. The upper limit is 100.

--exclusive-start-stream-arn (string)

The ARN (Amazon Resource Name) of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedStreamArn in the previous operation.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To list DynamoDB streams

The following list-streams command lists all existing Amazon DynamoDB streams within the default AWS Region.

aws dynamodbstreams list-streams

Output:

{
    "Streams": [
        {
            "StreamArn": "arn:aws:dynamodb:us-west-1:123456789012:table/Music/stream/2019-10-22T18:02:01.576",
            "TableName": "Music",
            "StreamLabel": "2019-10-22T18:02:01.576"
        }
    ]
}

For more information, see Capturing Table Activity with DynamoDB Streams in the Amazon DynamoDB Developer Guide.

Output

Streams -> (list)

A list of stream descriptors associated with the current account and endpoint.

(structure)

Represents all of the data describing a particular stream.

StreamArn -> (string)

The Amazon Resource Name (ARN) for the stream.

TableName -> (string)

The DynamoDB table with which the stream is associated.

StreamLabel -> (string)

A timestamp, in ISO 8601 format, for this stream.

Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:

• the AWS customer ID.

• the table name

• the StreamLabel

LastEvaluatedStreamArn -> (string)

The stream ARN of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedStreamArn is empty, then the “last page” of results has been processed and there is no more data to be retrieved.

If LastEvaluatedStreamArn is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedStreamArn is empty.
