(Either an explicit parameter or a new config, but either way, it requires changes to the application code.) I don't think that's a very good idea. It requires changes in user's applications for it to work, which makes it hard to run the same application against different clusters, for example. I think if you could do the mapping entirely in the config, and let the application just define the broker it wants to use, that's much much better. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
