> 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).
