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

Hi Sebastian,

Recently we upgraded exactly from same version to that version, and you need just two rolling restarts if you want two keep same log format version, or three to upgrade that version too.

Personally, I would recommend you to keep those properties, for example you could keep the current log format version for compatibility with old clients versions.

Hey guys,

I wonder what I should do with both settings for future upgrades after
having finished the upgrade from 0.10.1 to 2.1.1.

Should I just remove it from the config so it will default to the
current version of Kafka or do I have to do the rolling upgrade with
changing versions and restarting Kafka three times each time?

Thanks

Sebastian
