> The {{DispatcherThreadFactory}} is responsible for spawning the thread pool threads for TaskManager's async dispatcher and for the CheckpointCoordinators timed trigger.
> In case of uncaught exceptions in these threads, the system is not healthy and more, hence they should register the {{FatalExitUcaughtExceptionsHandler}}.
