Hey Randall, We just discovered another regression in 2.6: https://issues.apache.org/jira/browse/KAFKA-10249
The fix is extremely straightforward -- only about two lines of actual code -- and low risk. It is a new regression introduced in 2.6 and affects all Streams apps with any suppression or other in-memory state. The PR is already ready here: https://github.com/apache/kafka/pull/8996 Best, Sophie On Wed, Jul 8, 2020 at 10:59 AM John Roesler <vvcep...@apache.org> wrote: > Hi Randall, > > While developing system tests, I've just unearthed a new 2.6 regression: > https://issues.apache.org/jira/browse/KAFKA-10247 > > I've got a PR in progress.
