Upgrading Kafka from 0.9.0.1 to 0.10.0.1

Development
1

I was wondering what the timeline was for upgrading kafka from 9 to 10. If that was in the plans for the next graylog minor release (2.3.2) or major release (2.4). There are some bugs (connection issues) in kafka 9 that are causing production issues in graylog.

There are currently no plans to upgrade Kafka.

If you have problems with the currently used version of Kafka in Graylog, please open bug reports for each problem at https://github.com/Graylog2/graylog2-server/issues

@jochen… the reason why I am wanting to upgrade kafka is because it handles traffic better when it is has high volume.
