Hello all, I am writing a producer client for the v0.8 protocol. I have the wire format encoding working, and much of the functionality works well. However, I have made too many assumptions along the way, and it's time that I figure out the answers to these things. Sorry for the 'laundry list' -- most of them are related, and can possibly be answered in batch form.
TopicMetadata updates - is there a particular expectation of polling frequency? (per topic, per broker, etc.?) - should a particular topic's metadata request only go to the "current" leader of that topic? - if such a request fails to receive response, is there a particular expected behavior? - I am assuming that producers always push to the leader (feels like it's in the docs someplace, but can't confirm) - if the leader changes, what is the protocol for a producer? must the producer await ACK from outstanding requests before making a change, and if so, presumeably re-push those requests? I'm sure there will be more, but this opens the door. Cheers, ben
