class Aws::KinesisAnalyticsV2::Types::ParallelismConfiguration

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].

@note When making an API call, you may pass ParallelismConfiguration

data as a hash:

    {
      configuration_type: "DEFAULT", # required, accepts DEFAULT, CUSTOM
      parallelism: 1,
      parallelism_per_kpu: 1,
      auto_scaling_enabled: false,
    }

@!attribute [rw] configuration_type

Describes whether the application uses the default parallelism for
the Kinesis Data Analytics service. You must set this property to
`CUSTOM` in order to change your application's
`AutoScalingEnabled`, `Parallelism`, or `ParallelismPerKPU`
properties.
@return [String]

@!attribute [rw] parallelism

Describes the initial number of parallel tasks that a Flink-based
Kinesis Data Analytics application can perform. If
`AutoScalingEnabled` is set to True, Kinesis Data Analytics
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 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.
@return [Integer]

@!attribute [rw] parallelism_per_kpu

Describes the number of parallel tasks that a Flink-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][1].

@return [Integer]

@!attribute [rw] auto_scaling_enabled

Describes whether the Kinesis Data Analytics service can increase
the parallelism of the application in response to increased
throughput.
@return [Boolean]
