Re: [EXTERNAL] Handling of inter.broker.protocol.version and lo.message.format.version after upgrading

Hi Manuel,

thanks. I did the three rolling restarts, or in my case three
deployments of containers with different config... But the question now
is if I should do these three restarts each time I update to latest
Kafka or if I now just change both versions to latest one without having
to do three restarts as it's just a small change and not two major versions.
I already upgraded Kafka itself from 2.1.1 to 2.3.0 in the meantime, but
still use 2.1-IV2 as Version for the log.message.format and
inter.broker.protocol... So should I do two more deployments with each
one changing one version at a time or just bump everything up to 2.3-IV1
in one go for next config-change-deployment?

Thanks

Sebastian
