Hi Markus, Big +1 for upgrading. In my case we use blue/green deployments so that would be fine.
The only potential problem is on the DCOS package for Mesos, for supporting the latest Kafka version; i think it should work OOTB, but until it’s tested I’m leaving room for unknowns. Would you know if the Kafka client library is able to handle both versions ?
