Subject [jira] [Commented] (S4-45) UDP should use Netty
Date Sun, 03 Mar 2013 18:25:12 GMT


Karthik Kambatla commented on S4-45:

On S4-15, Matthieu suggested we don't have a configuration mechanism just yet. My understanding
was S4 would use file to configure this. Is that approach still valid?
If yes, I can go ahead and add the code to configure it. Otherwise, I am not sure what is
a good way to go about it.

If we have to go round about to add UDP support, I see the following options:
# If we think UDP is not worth supporting, I think we need to make a conscious decision and
close this JIRA out as "Won't Fix".
# If we think we might want to support UDP in the future but not as an immediate priority,
we should probably get the implementation in now and add the configurability later? Just to
make sure the work to port/refactor doesn't go to a waste only to be done again later.

Either way, the committers should probably make a decision here.

> UDPEmitter and UDPListener use our own implementation suffering from the following issues
> 1. All send() calls are essentially serialized
> 2. If the listener thread is interrupted, it doesn't restart listening.
> Using Netty will solve the above-mentioned issues while making the code more maintainable
as both UDP and TCP would then be using Netty.
> Comments or suggestions?
