Expand description
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.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.configuration_type: Option<ConfigurationType>
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.
parallelism: Option<i32>
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.
parallelism_per_kpu: Option<i32>
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.
auto_scaling_enabled: Option<bool>
Describes whether the Kinesis Data Analytics service can increase the parallelism of the application in response to increased throughput.
