  • Method Details

    • configurationType

      public final ConfigurationType 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.

      If the service returns an enum value that is not available in the current SDK version, configurationType will return ConfigurationType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from configurationTypeAsString().

      Returns:
      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.

    • parallelism

      public final Integer 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 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.

    • parallelismPerKPU

      public final Integer 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.

      Returns:

    • autoScalingEnabled

      public final Boolean autoScalingEnabled()

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

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

    • toBuilder

      public ParallelismConfiguration.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<ParallelismConfiguration.Builder,ParallelismConfiguration>
      Returns:
      a builder for type T

    • builder

      public static ParallelismConfiguration.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ParallelismConfiguration.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
