Dirk, we included the note "be careful when using Kafka Streams in production" because Kafka Streams as shipped in Kafka 0.10.0.0 is the first-ever release of Kafka Streams. In practice, users are running Streams applications in a variety of stages -- some are doing pilots or evaluations, some are already running it in production.
The 0.10.x release line will see bug fixes and improvements (as you'd expect) but may also bring bigger new functionality such as Queryable State [1]. Hope this helps, Michael [1] https://cwiki.apache.org/confluence/display/KAFKA/KIP-67%3A+Queryable+state+for+Kafka+Streams On Mon, Jul 4, 2016 at 11:14 AM, Dirk Jeßberger <dirk.jessber...@1und1.de> wrote: > Hello, > > According to the FAQ (http://docs.confluent.io/3.0.0/streams/faq.html) > it is not recommended to use Kafka Stream for production.
