[ aws . kinesisanalyticsv2 ]

start-application

Description

Starts the specified Kinesis Data Analytics application. After creating an application, you must exclusively call this operation to start your application.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  start-application
--application-name <value>
[--run-configuration <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--application-name (string)

The name of the application.

--run-configuration (structure)

Identifies the run configuration (start parameters) of a Kinesis Data Analytics application.

FlinkRunConfiguration -> (structure)

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

(structure)

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

InputId -> (string)

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

InputStartingPositionConfiguration -> (structure)

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 -> (structure)

Describes the restore behavior of a restarting application.

ApplicationRestoreType -> (string)

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 .

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.
