Subject [jira] [Commented] (S4-45) UDP should use Netty
Date Sun, 03 Mar 2013 18:43:12 GMT


Matthieu Morel commented on S4-45:

We did have a configuration mechanism for switching between transports. However, we also refactored
the way we configured applications, and in order to handle app-specific events, the listener
implementation can only be loaded in the AppModule, i.e. through a app-aware classloader.
And currently the listener is hardcoded in that module to TCPListener.

There are certainly various means to enable configurability, but currently I'd rather postpone
that to a later release (>0.6).

> 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?
