IsTimeForResize(Int64)

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.

Declaration
public abstract bool IsTimeForResize(long messageCounter)
Parameters
Type Name Description
Int64 messageCounter

TBD
Returns
Type Description
Boolean
