John,
Storm has various streams groupings to achieve this. Read the "Streams
Groupings" paragraph. If that doesn't answer your question, please let me know.

Awesome, thanks everyone! Annabel -> I should have clarified my question
better, I meant to ask if there are multiple streams defined between two
bolts whether both streams would go over the same connection. I have logic
that will send one of two types of streams between two bolts depending upon

Pretty sure it's using one port for all of the communications. Also ZMQ is
not a queue, especially not a brokered one, and storm uses netty by default
in the latest versions.

John,
It depends on how you defined your topology. If you created a topology made of
one spout, two streams and a bolt, then the data received from the spout is
going to go down to the bolt via those two streams. Spouts and bolts are
connected through streams.
Thanks

Hi John ,
I am not aware of the storm internal working so I am not sure about this .
But since no one has answered this so far , I will try my hand .
I believe Spouts and Bolts communicate through an intermediate queue (ZMQ)
. Assuming this it should always be a single connection to ZMQ .
But Li
Hi Everyone,
Had a co-worker ask me today if, I define two output streams for a spout or
bolt, do they both go out over the same connection to a downstream bolt, or
are there separate connections for each output stream.
Anyone know?
Thanks
