I plan to upgrade both the server and clients to 0.9. Had a few questions before I went ahead with the upgrade:
1. Do all brokers need to be on 0.9? Currently we are running 0.8.2. We'd ideally like to convert only a few brokers to 0.9 and only if we don't see problems convert the rest. 2. Is it possible to run Kafka 0.9 clients (specifically the consumer) with Kafka 0.8.2 brokers? Any link to the upgrade path would be really useful. Thanks, Rajiv
