- AutoScalingEnabledUpdate
-
Describes updates to whether the Managed Service for Apache Flink service can increase the parallelism of a Managed Service for Apache Flink application in response to increased throughput.
Type: Boolean
Required: No
- ConfigurationTypeUpdate
-
Describes updates to whether the application uses the default parallelism for the Managed Service for Apache Flink service, or if a custom parallelism is used. You must set this property to
CUSTOM
in order to change your application'sAutoScalingEnabled
,Parallelism
, orParallelismPerKPU
properties.Type: String
Valid Values:
DEFAULT | CUSTOM
Required: No
- ParallelismPerKPUUpdate
-
Describes updates to the number of parallel tasks an application can perform per Kinesis Processing Unit (KPU) used by the application.
Type: Integer
Valid Range: Minimum value of 1.
Required: No
- ParallelismUpdate
-
Describes updates to the initial number of parallel tasks an application can perform. If
AutoScalingEnabled
is set to True, then Managed Service for Apache Flink can increase theCurrentParallelism
value in response to application load. The service can increaseCurrentParallelism
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 will reduceCurrentParallelism
down to theParallelism
setting.Type: Integer
Valid Range: Minimum value of 1.
Required: No
