> Currently, SyncProducer has a few parameters that control how long the client should wait to establish a socket connection and how frequent the connection should be re-established. Those parameters seem to be needed primarily for vip on a load balancer. In 0.8, SyncProducer doesn't deal with VIP any more. So, we probably should get rid of those parameters. One of the issues that I have seen is that when a broker is down, SyncProducer will still wait connectionTimeout time to try to establish a connection. This is unnecessary since the high level producer already has the retry logic and is delaying requests like getMetadataRequest.
