Akka.NETSourceOperationsGroupedWithinTOut, TMat Method
Chunk up this stream into groups of elements received within a time window, or limited by the given number of elements, whatever happens first. Empty groups will not be emitted if no elements are received from upstream. The last group before end-of-stream will contain the buffered elements since the previously emitted group. n must be positive, and timeout must be greater than 0 seconds, otherwise ArgumentException is thrown.

Emits when the configured time elapses since the last group has been emitted

Backpressures when the configured time elapses since the last group has been emitted

Completes when upstream completes (emits last group)

Cancels when downstream completes
