Abstract Value Members

  1. abstract def isTimeForResize(messageCounter: Long): Boolean

    Is it time for resizing.

    Is it time for resizing. Typically implemented with modulo of nth message, but could be based on elapsed time or something else. The messageCounter starts with 0 for the initial resize and continues with 1 for the first message. Make sure to perform initial resize before first message (messageCounter == 0), because there is no guarantee that resize will be done when concurrent messages are in play.

    CAUTION: this method is invoked from the thread which tries to send a message to the pool, i.e. the ActorRef.!() method, hence it may be called concurrently.

  2. abstract def resize(currentRoutees: IndexedSeq[Routee]): Int

    Decide if the capacity of the router need to be changed.

    Decide if the capacity of the router need to be changed. Will be invoked when isTimeForResize returns true and no other resize is in progress.

    Return the number of routees to add or remove. Negative value will remove that number of routees. Positive value will add that number of routess. 0 will not change the routees.

    This method is invoked only in the context of the Router actor.
