Subject [jira] [Commented] (S4-15) Picking a communication protocol
Date Thu, 20 Oct 2011 05:55:11 GMT


Karthik Kambatla commented on S4-15:

This ties very well to the Netty initialization problem as well. Though the netty-initialization
can be solved in other ways, the order of creating Listener and Emitter instances can solve
the problem.

We want the NettyListener to be created first so that the NettyEmitter can connect to it.
Bruce had to move the connections part of the emitter to a different thread to allow Listener

> 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.

classes should be automatically picked.
