Subject [jira] [Commented] (S4-15) Picking a communication protocol
Date Sat, 22 Oct 2011 01:24:32 GMT

    [ https://issues.apache.org/jira/browse/S4-15?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13133212#comment-13133212

kishore gopalakrishna commented on S4-15:
-----------------------------------------

This can be solved in the distributed mode by actually having the mode in the task. The emitter
can always  chose the right emitter based on the listening mode of the listener node. 

In S4 as a service, we can actually support  multiple protocols. And the stream can specify
the mode of transport and we chose appropriate protocol. This will be very powerful because
in general getting events into the system will use a different protocol and once they are
in s4 they will use a different protocol.

> 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.
