final class Partition[T] extends GraphStage[UniformFanOutShape[T, T]]
Fan-out the stream to several streams. emitting an incoming upstream element to one downstream consumer according to the partitioner function applied to the element
Emits when emits when an element is available from the input and the chosen output has demand
Backpressures when the currently chosen output back-pressures
Completes when upstream completes and no output is pending
Cancels when when all downstreams cancel
