QLDB / Client / list_journal_kinesis_streams_for_ledger



Returns an array of all Amazon QLDB journal stream descriptors for a given ledger. The output of each stream descriptor includes the same details that are returned by DescribeJournalKinesisStream.

This action does not return any expired journal streams. For more information, see Expiration for terminal streams in the Amazon QLDB Developer Guide.

This action returns a maximum of MaxResults items. It is paginated so that you can retrieve all the items by calling ListJournalKinesisStreamsForLedger multiple times.

Request Syntax

response = client.list_journal_kinesis_streams_for_ledger(
  • LedgerName (string) –


    The name of the ledger.

  • MaxResults (integer) – The maximum number of results to return in a single ListJournalKinesisStreamsForLedger request. (The actual number of results returned might be fewer.)

  • NextToken (string) – A pagination token, indicating that you want to retrieve the next page of results. If you received a value for NextToken in the response from a previous ListJournalKinesisStreamsForLedger call, you should use that value as input here.

Response Structure

  • (dict) –

    • Streams (list) –

      The array of QLDB journal stream descriptors that are associated with the given ledger.

      • (dict) –

        Information about an Amazon QLDB journal stream, including the Amazon Resource Name (ARN), stream name, creation time, current status, and the parameters of the original stream creation request.

        • LedgerName (string) –

          The name of the ledger.

        • CreationTime (datetime) –

          The date and time, in epoch time format, when the QLDB journal stream was created. (Epoch time format is the number of seconds elapsed since 12:00:00 AM January 1, 1970 UTC.)

        • InclusiveStartTime (datetime) –

          The inclusive start date and time from which to start streaming journal data.

        • ExclusiveEndTime (datetime) –

          The exclusive date and time that specifies when the stream ends. If this parameter is undefined, the stream runs indefinitely until you cancel it.

        • RoleArn (string) –

          The Amazon Resource Name (ARN) of the IAM role that grants QLDB permissions for a journal stream to write data records to a Kinesis Data Streams resource.

        • StreamId (string) –

          The UUID (represented in Base62-encoded text) of the QLDB journal stream.

        • Arn (string) –

          The Amazon Resource Name (ARN) of the QLDB journal stream.

        • Status (string) –

          The current state of the QLDB journal stream.

        • KinesisConfiguration (dict) –

          The configuration settings of the Amazon Kinesis Data Streams destination for a QLDB journal stream.

          • StreamArn (string) –

            The Amazon Resource Name (ARN) of the Kinesis Data Streams resource.

          • AggregationEnabled (boolean) –

            Enables QLDB to publish multiple data records in a single Kinesis Data Streams record, increasing the number of records sent per API call.

            This option is enabled by default. Record aggregation has important implications for processing records and requires de-aggregation in your stream consumer. To learn more, see KPL Key Concepts and Consumer De-aggregation in the Amazon Kinesis Data Streams Developer Guide.

        • ErrorCause (string) –

          The error message that describes the reason that a stream has a status of IMPAIRED or FAILED. This is not applicable to streams that have other status values.

        • StreamName (string) –

          The user-defined name of the QLDB journal stream.

    • NextToken (string) –

      • If NextToken is empty, the last page of results has been processed and there are no more results to be retrieved.

      • If NextToken is not empty, more results are available. To retrieve the next page of results, use the value of NextToken in a subsequent ListJournalKinesisStreamsForLedger call.
