Hello folks, I've created a new KIP allowing consumer.committed to take a set of partitions instead of just one partition to allow batching effects of such requests (the protocol already allows us to send multiple partitions in one round-trip):
https://cwiki.apache.org/confluence/display/KAFKA/KIP-520%3A+Add+overloaded+Consumer%23committed+for+batching+partitions Since it is a pretty straight-forward KIP, I'm starting the VOTE for this KIP directly. If there are any suggestions about this proposal, please feel free to share them in this thread. Thank you! -- Guozhang
