Executor Service Configuration

Following are the example configurations for executor service.

Declarative:

<executor-service name="exec">
   <pool-size>1</pool-size>
   <queue-capacity>10</queue-capacity>
   <statistics-enabled>true</statistics-enabled>
</executor-service>

Programmatic:

Config config = new Config();
ExecutorConfig executorConfig = config.getExecutorConfig();
executorConfig.setPoolSize( "1" ).setQueueCapacity( "10" )
          .setStatisticsEnabled( true );

Executor service configuration has the following elements.

  • pool-size: The number of executor threads per Member for the Executor.
  • queue-capacity: Executor's task queue capacity.
  • statistics-enabled: Some statistics like pending operations count, started operations count, completed operations count, cancelled operations count can be retrieved by setting this parameter's value as true. The method for retrieving the statistics is getLocalExecutorStats().
