Hey guys, Two quick things: 1. There is a proposed change to ProducerData to allow us to retain the partition key with the message here: https://issues.apache.org/jira/browse/KAFKA-544 This would also mean changing the Encoder/Decoder interface. Since this impacts the user-facing APIs I think it would be useful to get any feedback up front before I write a bunch of code. 2. There is another JIRA to make the producer return the offset(s) to the caller. Since these are both in the same chunk of code, I would like to grab this if no one else is actively working on it to avoid merge hell. https://issues.apache.org/jira/browse/KAFKA-496
