Thanks Mickael. I ran the following: 1. Verified the signature and checksum for kafka_2.13-4.1.0.tgz and kafka-4.1.0-src.tgz. 2. Ran the quickstart. 3. Ran the kafka-console-share-consumer.sh without feature flag toggle to confirm share groups feature is not supported, and appropriate error message is displayed. 4. Enabled share groups using feature flag using: kafka-features.sh --bootstrap-server localhost:9092 upgrade --feature share.version=1 5. Produced messages using kafka-producer-perf-test.sh. 6. Ran multiple kafka-console-share-consumer.sh in the same share group, reading from single partition to test sharing.
All of the above tests were successful. +1 (non-binding) Regards, Apoorv Mittal On Tue, Aug 19, 2025 at 5:11 PM Kuan-Po Tseng <brandb...@apache.org> wrote: > Hi Mickael, > > I did the following: > - Built from 4.1.0-rc2 with 23.0.2-zulu > - Ran all unit and integration tests > - Validated the checksums and keys > - Run quick start with KRaft > - Run kafka streams demo application > > All of the above tests completed successfully. > > +1 (non-binding) > > Thank you! > Kuan-Po Tseng > > On Tue, Aug 19, 2025 at 6:36 AM Justine Olshan > <jols...@confluent.io.invalid> > wrote: > > > Thanks Mickael and sorry for the delay, > > > > I've done the following: > > 1.
