final class Balance[T] extends GraphStage[UniformFanOutShape[T, T]]

Fan-out the stream to several streams. Each upstream element is emitted to the first available downstream consumer. It will not shut down until the subscriptions for at least two downstream subscribers have been established.

A Balance has one in port and 2 or more out ports.

Emits when any of the outputs stops backpressuring; emits the element to the first available output

Backpressures when all of the outputs backpressure

Completes when upstream completes

Cancels when If eagerCancel is enabled: when any downstream cancels; otherwise: when all downstreams cancel

  6. def 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.
