final case class WatermarkRequestStrategy(highWatermark: Int, lowWatermark: Int) extends RequestStrategy with Product with Serializable
Requests up to the highWatermark
when the remainingRequested
is
below the lowWatermark
. This a good strategy when the actor performs work itself.

- remainingRequested
current remaining number of elements that have been requested from upstream but not received yet
- returns
