There are some breaking API changes form 0.10.0 -> 0.10.1, so you may need to change some code. I'd also suggest you thoroughly test with the new version to ensure there are no regressions. There is a known issue with caching that may or may not effect you. It depends on your topology. https://issues.apache.org/jira/browse/KAFKA-4311 - there is a fix for it that will hopefully be merged to trunk and 0.10.1 soon, however i don't have any timeline for when/if a 0.10.1.1 release will be done. The config parameter is StreamsConfig.CACHE_MAX_BYTES_BUFFERING. You should also take a look at https://cwiki.apache.org/confluence/display/KAFKA/KIP-63%3A+Unify+store+and+downstream+caching+in+streams Thanks, Damian On Fri, 4 Nov 2016 at 09:44 Hamza HACHANI <hamza.hach...@supcom.tn> wrote: > Hi Damian, > > > If i would pass tp the 0.10.1.
