        'FlinkRunConfiguration': {

        },

            {
                'InputId': 'string',

        }
    }

Parameters:

  • ApplicationName (string) –

    [REQUIRED]

    The name of the application.

  • RunConfiguration (dict) –

    Identifies the run configuration (start parameters) of a Managed Service for Apache Flink application.

    • FlinkRunConfiguration (dict) –

      Describes the starting parameters for a Managed Service for Apache Flink application.

      • AllowNonRestoredState (boolean) –

        When restoring from a snapshot, specifies whether the runtime is allowed to skip a state that cannot be mapped to the new program. This will happen if the program is updated between snapshots to remove stateful parameters, and state data in the snapshot no longer corresponds to valid application data. For more information, see Allowing Non-Restored State in the Apache Flink documentation.

        Note

        This value defaults to false. If you update your application without specifying this parameter, AllowNonRestoredState will be set to false, even if it was previously set to true.

    • SqlRunConfigurations (list) –

      Describes the starting parameters for a SQL-based Kinesis Data Analytics application application.

      • (dict) –

        Describes the starting parameters for a SQL-based Kinesis Data Analytics application.

        • InputId (string) – [REQUIRED]

          The input source ID. You can get this ID by calling the DescribeApplication operation.

        • InputStartingPositionConfiguration (dict) – [REQUIRED]

          The point at which you want the application to start processing records from the streaming source.

          • InputStartingPosition (string) –

            The starting position on the stream.

            • NOW - Start reading just after the most recent record in the stream, and start at the request timestamp that the customer issued.

            • TRIM_HORIZON - Start reading at the last untrimmed record in the stream, which is the oldest record available in the stream. This option is not available for an Amazon Kinesis Data Firehose delivery stream.

            • LAST_STOPPED_POINT - Resume reading from where the application last stopped reading.

    • ApplicationRestoreConfiguration (dict) –

      Describes the restore behavior of a restarting application.

      • ApplicationRestoreType (string) – [REQUIRED]

        Specifies how the application should be restored.

      • SnapshotName (string) –

        The identifier of an existing snapshot of application state to use to restart an application. The application uses this value if RESTORE_FROM_CUSTOM_SNAPSHOT is specified for the ApplicationRestoreType.
