Contents
- 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'sAutoScalingEnabled
,Parallelism
, orParallelismPerKPU
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 theCurrentParallelism
value in response to application load. The service can increase theCurrentParallelism
value up to the maximum parallelism, which isParalellismPerKPU
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 theCurrentParallelism
value down to theParallelism
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
