Re: Out of order messages when kafka streams application catches up

Hi Tomasz, Thanks for asking. This sounds like the situation that we fixed in Apache Kafka 3.0, with KIP-695 (https://cwiki.apache.org/confluence/display/KAFKA/KIP-695%3A+Further+Improve+Kafka+Streams+Timestamp+Synchronization). Can you try upgrading and let us know if this fixes the problem?

Copy data from source cluster to target with different number of partitions

Hi, We have a cluster with topics that contain many partitions. We are going to decrease the number of partitions and looking for any solution. I t would be very useful to make it with MirrorMaker 2 but as we can see, it doesn't allow us to do it. MM2 creates missing partitions for a topic, e.g. s

Re: [VOTE] 3.3.0 RC2

+1 provided that the system test results are good. Can you please post them along with the JUnit test results (these seem ok although there are some flakes)? I tested the kraft quick start with the Scala 2.13 binary and ran the tests on the source release. I noticed a non-blocker issue with the KR

Thanks for running the release, José and David. I performed the following validations: * Verified all checksums and signatures. * Built from source and ran unit tests. * Ran the first quickstart steps for both ZK and KRaft. * Spotchecked the Javadocs. I have also noticed that the doc is malformed

Re: [VOTE] 3.3.0 RC2
