Subject: Re: commitOffsets by partition 0.8-beta

We don't have the ability to commit offset at the partition level now. This feature probably
won't be available until we are done with the consumer rewrite, which is 3-4 months away.

If you want to do sth now and don't want to use SimpleConsumer, another hacky way is to turn
off auto offset commit and write the offset to ZK in the right path yourself in the app.

Thanks,

Jun
