class SmallestMailboxRoutingLogic extends RoutingLogic

Tries to send to the non-suspended routee with fewest messages in mailbox. The selection is done in this order:

  • pick any idle routee (not processing message) with empty mailbox
  • pick any routee with empty mailbox
  • pick routee with fewest pending messages in mailbox
  • pick any remote routee, remote actors are consider lowest priority, since their mailbox size is unknown

    Returns true if the actor currently has any pending messages in the mailbox, i.e. the mailbox is not empty. It will always return false for remote actors. Method is exposed to subclasses to be able to implement custom routers based on mailbox and actor internal state.

  25. def select(message: Any, routees: IndexedSeq[Routee]): Routee

    Pick the destination for a given message.

    Pick the destination for a given message. Normally it picks one of the passed routees, but in the end it is up to the implementation to return whatever pekko.routing.Routee to use for sending a specific message.

    When implemented from Java it can be good to know that routees.apply(index) can be used to get an element from the IndexedSeq.
