DropOldAndSignal

final case class DropOldAndSignal[A](bufferSize: Int, onOverflow: (Long) ⇒ Option[A]) extends Evicted[A] with Product with Serializable

A OverflowStrategy specifying that on reaching the maximum size, the currently buffered events should start being dropped in a FIFO order, so the oldest events from the buffer will be dropped first.

The given onOverflow function get be used for logging the event and for sending a message to the downstream consumers to inform them of dropped messages. The function can return None in which case no message is sent and thus you can use it just to log a warning.

bufferSize

specifies how many events our buffer can hold before overflowing

onOverflow

is a function that can get called on overflow with a number of messages that were dropped, a function that builds a new message that will be sent to downstream. If it returns None, then no message gets sent to downstream.
