– Mailboxes: Any, creates one per Actor

– Use cases: Default dispatcher, Bulkheading

– Driven by: java.util.concurrent.ExecutorService specify using “executor” using “fork-join-executor”, “thread-pool-executor” or the FQCN of an

akka.dispatcher.ExecutorServiceConfigurator

• PinnedDispatcher

– This dispatcher dedicates a unique thread for each actor using it; i.e. each actor will have its own thread pool with only one thread in the pool.

– Sharability: None

– Mailboxes: Any, creates one per Actor

– Use cases: Bulkheading

– Driven by: Any akka.dispatch.ThreadPoolExecutorConfigurator by default a“thread-pool-executor”

• CallingThreadDispatcher

– This dispatcher runs invocations on the current thread only. This dispatcher does not create any new

threads, but it can be used from different threads concurrently for the same actor. See CallingThreadDispatcher for details and restrictions.

– Sharability: Unlimited

– Mailboxes: Any, creates one per Actor per Thread (on demand)

– Use cases: Testing

– Driven by: The calling thread (duh)

Akka官方文档中说有四个，只找到三个。
