ParallelismConfiguration

Describes parameters for how a Managed Service for Apache Flink application executes multiple tasks simultaneously. For more information about parallelism, see Parallel Execution in the Apache Flink Documentation.

ConfigurationType

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.

Type: String

Valid Values: DEFAULT | CUSTOM

Required: Yes

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

Parallelism

Describes the initial 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 increases the CurrentParallelism value in response to application load. The service can increase the CurrentParallelism 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

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. For more information about KPUs, see Amazon Managed Service for Apache Flink Pricing.

Type: Integer

Valid Range: Minimum value of 1.

Required: No
