Description
Currently, the layer only works on single stream and ignores stream names, ie, each stream is treated as "default" stream. The declaration of multiple output streams is ignored (all tuples are emitted to the same stream). If multiple input streams are consumed all tuples are merged into a single stream.
This feature allows operators to declare multiple (named) output streams and emit tuples to different stream. Furthermore, it enables Bolts to distinguish incoming tuples from different streams by stream name (Storm tuple meta information).
