I have been using Kafka 0.8.2 in a production setting for consuming real-time event traffic from our caching layer for six months. The most difficult parts of my experience were the occasional consumer lags that erupted without warning/cause in the high level Java consumer APIs. A lot of experimentation with their configuration proved to be futile and now we have had to create a feedback system that triggers alerts to change group Ids of our high level consumers every time some consumers start lagging.

Otherwise the performance of Kafka has been impressive (giving a throughput of upto 15000 packets/sec to a 8-consumer pool), even though I have not had the chance to compare it with any other such tool/library.

Nevertheless, I think this update is a long awaited one, and Kafka Connect may really be good starting point for building more (and better) endpoints.

In this case, you will enjoy the new consumer in 0.9 a lot!
