list-journal-kinesis-streams-for-ledger

Description

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

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  list-journal-kinesis-streams-for-ledger
--ledger-name <value>
[--max-results <value>]
[--next-token <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--ledger-name (string)

The name of the ledger.

--max-results (integer)

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

--next-token (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.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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 journal streams for a ledger

The following list-journal-kinesis-streams-for-ledger example lists journal streams for the specified ledger.

aws qldb list-journal-kinesis-streams-for-ledger \
    --ledger-name myExampleLedger

Output:

{
    "Streams": [
        {
            "LedgerName": "myExampleLedger",
            "CreationTime": 1591221984.677,
            "InclusiveStartTime": 1590710400.0,
            "ExclusiveEndTime": 1590796799.0,
            "RoleArn": "arn:aws:iam::123456789012:role/my-kinesis-stream-role",
            "StreamId": "7ISCkqwe4y25YyHLzYUFAf",
            "Arn": "arn:aws:qldb:us-east-1:123456789012:stream/myExampleLedger/7ISCkqwe4y25YyHLzYUFAf",
            "Status": "ACTIVE",
            "KinesisConfiguration": {
                "StreamArn": "arn:aws:kinesis:us-east-1:123456789012:stream/stream-for-qldb",
                "AggregationEnabled": true
            },
            "StreamName": "myExampleLedger-stream"
        }
    ]
}

Output

Streams -> (list)

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

(structure)

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

LedgerName -> (string)

The name of the ledger.

CreationTime -> (timestamp)

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 -> (timestamp)

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

ExclusiveEndTime -> (timestamp)

The exclusive date and time that specifies when the stream ends. If this parameter is blank, 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 unique ID that QLDB assigns to each 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 -> (structure)

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

StreamArn -> (string)

The Amazon Resource Name (ARN) of the Kinesis data stream resource.

AggregationEnabled -> (boolean)

Enables QLDB to publish multiple data records in a single Kinesis Data Streams record. To learn more, see KPL Key Concepts 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.
