The following are example configurations for executor service.


<executor-service name="exec">


Config config = new Config();
ExecutorConfig executorConfig = config.getExecutorConfig("exec");
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. By default, Executor is configured to have 16 threads in the pool. You can change that with this element.
  • queue-capacity: Executor's task queue capacity; the number of tasks this queue can hold.
  • statistics-enabled: You can retrieve some statistics (such as pending operations count, started operations count, completed operations count, and cancelled operations count) by setting this parameter's value to true. The method for retrieving the statistics is getLocalExecutorStats().
