Akka.NETFlowOperationsBatchTIn, TOut, TOut2, TMat Method
Allows a faster upstream to progress independently of a slower subscriber by aggregating elements into batches until the subscriber is ready to accept them.For example a batch step might store received elements in an array up to the allowed max limit if the upstream publisher is faster. This only rolls up elements if the upstream is faster, but if the downstream is faster it will not duplicate elements. Emits when downstream stops backpressuring and there is an aggregated element available Backpressures when there are max batched elements and 1 pending element and downstream backpressures Completes when upstream completes and there is no batched/pending element waiting Cancels when downstream cancels See also ,

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type FlowTIn, TOut, TMat. When you use instance method syntax to call this method, omit the first parameter.
