WildFly 14.0 Model Reference

  1. WildFly 14.0

  3. distributed-workmanager
  4. short-running-threads

A thread pool executor with a bounded queue where threads submittings tasks will not block. Such a thread pool has a core and maximum size and a specified queue length. When a task is submitted, if the number of running threads is less than the core size, a new thread is created. Otherwise, if there is room in the queue, the task is enqueued. Otherwise, if the number of running threads is less than the maximum size, a new thread is created. Otherwise, the task is handed off to the designated handoff executor, if one is specified. Otherwise, the task is discarded.
