/AWS1/CL_KN2PARALLELISMCONFDSC

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

CONSTRUCTOR

IMPORTING

Optional arguments:

iv_configurationtype TYPE /AWS1/KN2CONFIGURATIONTYPE /AWS1/KN2CONFIGURATIONTYPE

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

iv_parallelism TYPE /AWS1/KN2PARALLELISM /AWS1/KN2PARALLELISM

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 64 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.

iv_parallelismperkpu TYPE /AWS1/KN2PARALLELISMPERKPU /AWS1/KN2PARALLELISMPERKPU

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.

iv_currentparallelism TYPE /AWS1/KN2PARALLELISM /AWS1/KN2PARALLELISM

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.

iv_autoscalingenabled TYPE /AWS1/KN2BOOLEANOBJECT /AWS1/KN2BOOLEANOBJECT

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