Describes parameters for how a Flink-based Kinesis Data Analytics application executes multiple tasks simultaneously.

For more information about parallelism, see Parallel Execution in the Apache Flink Documentation .

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_kinesisanalytics as kinesisanalytics } from 'aws-cdk-lib';
const parallelismConfigurationProperty: kinesisanalytics.CfnApplicationV2.ParallelismConfigurationProperty = {
  configurationType: 'configurationType',

  // the properties below are optional
  autoScalingEnabled: false,
  parallelism: 123,
  parallelismPerKpu: 123,
};

Properties

Name	Type	Description
configurationType	`string`	Describes whether the application uses the default parallelism for the Managed Service for Apache Flink service.
autoScalingEnabled?	`boolean \|` `IResolvable`	Describes whether the Managed Service for Apache Flink service can increase the parallelism of the application in response to increased throughput.
parallelism?	`number`	Describes the initial number of parallel tasks that a Java-based Kinesis Data Analytics application can perform.
parallelismPerKpu?	`number`	Describes the number of parallel tasks that a Java-based Kinesis Data Analytics application can perform per Kinesis Processing Unit (KPU) used by the application.

configurationType

Type: string

Describes whether the application uses the default parallelism for the Managed Service for Apache Flink service.

You must set this property to CUSTOM in order to change your application's AutoScalingEnabled , Parallelism , or ParallelismPerKPU properties.

autoScalingEnabled?

Type: boolean | IResolvable (optional)

Describes whether the Managed Service for Apache Flink service can increase the parallelism of the application in response to increased throughput.

parallelism?

Type: number (optional)

Describes the initial number of parallel tasks that a Java-based Kinesis Data Analytics application can perform.

The Kinesis Data Analytics service can increase this number automatically if ParallelismConfiguration:AutoScalingEnabled is set to true .

parallelismPerKpu?

Type: number (optional)

Describes the number of parallel tasks that a Java-based Kinesis Data Analytics application can perform per Kinesis Processing Unit (KPU) used by the application.
