Partition

Companion object Partition

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
