Interface CfnApplicationV2.ParallelismConfigurationProperty

All Superinterfaces:

software.amazon.jsii.JsiiSerializable

All Known Implementing Classes:

CfnApplicationV2.ParallelismConfigurationProperty.Jsii$Proxy

Enclosing class:

CfnApplicationV2

@Stability(Stable)
public static interface CfnApplicationV2.ParallelismConfigurationProperty
extends software.amazon.jsii.JsiiSerializable

Describes parameters for how a Flink-based Kinesis Data Analytics application executes multiple tasks simultaneously.

For more information about parallelism, see Parallel Execution in the Apache Flink Documentation .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.kinesisanalytics.*;
 ParallelismConfigurationProperty parallelismConfigurationProperty = ParallelismConfigurationProperty.builder()
         .configurationType("configurationType")
         // the properties below are optional
         .autoScalingEnabled(false)
         .parallelism(123)
         .parallelismPerKpu(123)
         .build();

Method Details

getConfigurationType

@Stability(Stable)
@NotNull
String getConfigurationType()

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.

getAutoScalingEnabled

@Stability(Stable)
@Nullable
default Object getAutoScalingEnabled()

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

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisanalyticsv2-application-parallelismconfiguration.html#cfn-kinesisanalyticsv2-application-parallelismconfiguration-autoscalingenabled

getParallelism

@Stability(Stable)
@Nullable
default Number getParallelism()

Describes the initial number of parallel tasks that a Java-based Kinesis Data Analytics application can perform.

The Kinesis Data Analytics service can increase this number automatically if ParallelismConfiguration:AutoScalingEnabled is set to true .

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisanalyticsv2-application-parallelismconfiguration.html#cfn-kinesisanalyticsv2-application-parallelismconfiguration-parallelism

getParallelismPerKpu

@Stability(Stable)
@Nullable
default Number getParallelismPerKpu()

Describes the number of parallel tasks that a Java-based Kinesis Data Analytics application can perform per Kinesis Processing Unit (KPU) used by the application.

For more information about KPUs, see Amazon Kinesis Data Analytics Pricing .

builder

@Stability(Stable)
static CfnApplicationV2.ParallelismConfigurationProperty.Builder builder()

Returns:

a CfnApplicationV2.ParallelismConfigurationProperty.Builder of CfnApplicationV2.ParallelismConfigurationProperty
