Difference in performance on direct grouping

[Nick R. Katsipoulakis]

Hello,

I was wondering whether there is a performance gain if in the
declareOutputFields() of my spouts/bolts I use declareStream() instead of
declare()? In other words, if I give a hint to Storm that I am using direct
streams instead of letting the runtime figure it out by itself, will I see
better performance?

Thanks,
Nikos
