See thePartition companion object

final class Partition[T](val outputPorts: Int, val partitioner: T => Int, val eagerCancel: Boolean) 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

Adheres to the ActorAttributes.SupervisionStrategy attribute.

'''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''' all downstreams have cancelled (eagerCancel=false) or one downstream cancels (eagerCancel=true)

Inherited methods

Add the given attributes to this Graph. If the specific attribute was already present on this graph this means the added attribute will be more specific than the existing one. If this Source is a composite of multiple graphs, new attributes on the composite will be less specific than attributes set directly on the individual graphs of the composite.

Value parameters

dispatcher: Run the graph on this dispatcher
inputBufferSize: Set the input buffer to this size for the graph
