public class PriorityThreadsDispatcher
extends org.apache.pekko.dispatch.DispatcherConfigurator

Pekko dispatcher threads creates threads with configurable priority.

Example of configuration:

   low-priority-threads-dispatcher {
     type = org.apache.flink.runtime.rpc.pekko.PriorityThreadsDispatcher
     executor = "thread-pool-executor"
     # should be between Thread.MIN_PRIORITY (which is 1) and Thread.MAX_PRIORITY (which is 10)
     threads-priority = 1
     thread-pool-executor {
       core-pool-size-min = 0
       core-pool-size-factor = 2.0
       core-pool-size-max = 10
     }
   }
 

Two arguments constructor (the primary constructor) is automatically called by Pekko when it finds:

   abcde-dispatcher {
     type = org.apache.flink.runtime.rpc.pekko.PriorityThreadsDispatcher <-- the class that Pekko will instantiate
     ...
   }
