Otis, I wouldn't call 0.8 HEAD production ready right now, there are still some performance issues that we are working on. At LinkedIn, we are at least 2 months away from deploying 0.8 in production.

Not yet. 0.7.2 is very stable and is deployed in production for several months without problems. > * How stable or buggy is Kafka 0.8 HEAD? It is feature complete, and like I said, there are performance bugs like memory leaks, that we are working on. > * If we switch to using 0.8 now, what are the chances of incompatibilities in > terms of how data in Kafka is stored?

However, upgrading from 0.7.2 to 0.8 is also backwards incompatible and will require careful deployment planning to correctly release 0.8 without service interruptions.
