.. note::
Normally it should not be necessary to configure a separate dispatcher for the Cluster.
The default-dispatcher should be sufficient for performing the Cluster tasks, i.e. ``akka.cluster.use-dispatcher``
should not be changed. If you have Cluster related problems when using the default-dispatcher that is typically an
indication that you are running blocking or CPU intensive actors/tasks on the default-dispatcher.
Use dedicated dispatchers for such actors/tasks instead of running them on the default-dispatcher,
because that may starve system internal tasks.
Related config properties: ``akka.cluster.use-dispatcher = akka.cluster.cluster-dispatcher``.
Corresponding default values: ``akka.cluster.use-dispatcher =``.
