DynamoDBStreams / Client / list_streams

list_streams

DynamoDBStreams.Client.list_streams(**kwargs)

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.

Request Syntax

response = client.list_streams(
    TableName='string',
    Limit=123,
    ExclusiveStartStreamArn='string'
)

Parameters:

• TableName (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.

• ExclusiveStartStreamArn (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.

Return type:

dict

Returns:

Response Syntax

{
    'Streams': [
        {
            'StreamArn': 'string',
            'TableName': 'string',
            'StreamLabel': 'string'
        },
    ],
    'LastEvaluatedStreamArn': 'string'
}

Response Structure

• (dict) –

  Represents the output of a ListStreams operation.

  • Streams (list) –

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

    • (dict) –

      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 Amazon Web Services 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.

Exceptions

• DynamoDBStreams.Client.exceptions.ResourceNotFoundException

• DynamoDBStreams.Client.exceptions.InternalServerError

Examples

The following example lists all of the stream ARNs.

response = client.list_streams(
)

print(response)
