public class MiniDispatcher
extends Dispatcher

Mini Dispatcher which is instantiated as the dispatcher component by the JobClusterEntrypoint.

The mini dispatcher is initialized with a single JobGraph which it runs.

Depending on the ClusterEntrypoint.ExecutionMode, the mini dispatcher will directly terminate after job completion if its execution mode is ClusterEntrypoint.ExecutionMode#DETACHED.
