ParallelismConfigurationDescription - Amazon Managed Service for Apache Flink (formerly Amazon Kinesis Data Analytics for Apache Flink)
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

ParallelismConfigurationDescription

Describes parameters for how a Managed Service for Apache Flink application executes multiple tasks simultaneously.

Contents

AutoScalingEnabled

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

Type: Boolean

Required: No

ConfigurationType

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

Type: String

Valid Values: DEFAULT | CUSTOM

Required: No

CurrentParallelism

Describes the current number of parallel tasks that a Managed Service for Apache Flink application can perform. If AutoScalingEnabled is set to True, Managed Service for Apache Flink can increase this value in response to application load. The service can increase this value up to the maximum parallelism, which is ParalellismPerKPU times the maximum KPUs for the application. The maximum KPUs for an application is 32 by default, and can be increased by requesting a limit increase. If application load is reduced, the service can reduce the CurrentParallelism value down to the Parallelism setting.

Type: Integer

Valid Range: Minimum value of 1.

Required: No

Parallelism

Describes the initial number of parallel tasks that a Managed Service for Apache Flink application can perform. If AutoScalingEnabled is set to True, then Managed Service for Apache Flink can increase the CurrentParallelism value in response to application load. The service can increase CurrentParallelism up to the maximum parallelism, which is ParalellismPerKPU times the maximum KPUs for the application. The maximum KPUs for an application is 32 by default, and can be increased by requesting a limit increase. If application load is reduced, the service can reduce the CurrentParallelism value down to the Parallelism setting.

Type: Integer

Valid Range: Minimum value of 1.

Required: No

ParallelismPerKPU

Describes the number of parallel tasks that a Managed Service for Apache Flink application can perform per Kinesis Processing Unit (KPU) used by the application.

Type: Integer

Valid Range: Minimum value of 1.

Required: No
