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

addAttributes(attr: Attributes): Graph[UniformFanOutShape[T, T], NotUsed]
Add the given attributes to this Graph.
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.
