Subject [jira] [Commented] (S4-15) Picking a communication protocol
Date Sun, 03 Mar 2013 11:13:13 GMT


Matthieu Morel commented on S4-15:

Thanks Karthik for the patch. However a requirement for updating the udp transport is actually
to enable it.

Currently, TCP is the default and only protocol - see

I don't see a strong case for enabling udp at the moment, given the performance that we reach
with TCP and the configurable load shedding mechanisms now available in S4.

But if you have a suggestion / update to the patch to allow pluggable transport that would
be great and we could probably integrate it!

> Currently, the application (the associated module) require binding both the emitter and
listener classes. Such an approach allows improper selections - e.g. UDPEmitter for Emitter
and NettyListener for Listener.
> Instead, one should pick a communication protocol, the appropriate Emitter and Listener
classes should be automatically picked.
