final class Merge[T] extends GraphStage[UniformFanInShape[T, T]]

Merge several streams, taking elements as they arrive from input streams (picking randomly when several have elements ready).

Emits when one of the inputs has an element available

Backpressures when downstream backpressures

Completes when all upstreams complete (eagerComplete=false) or one upstream completes (eagerComplete=true), default value is false

Cancels when downstream cancels
