Hi Tina, Thanks for the KIP!
I hope someone with prior MM or Kafka config experience is able to chime in here; I have neither. I took a look at your KIP, and it makes sense to me. I also think your migration plan is a good one. One suggestion: I'm not sure how concerned you are about people's ability to migrate, but if you want to make it as smooth as possible, you could add one more step. In the 4.0 release, while removing `use.incremental.alter.configs`, you can also add `use.legacy.alter.configs` to give users a path to continue using the old behavior even after the default changes. Clearly, this will prolong the deprecation period, with implications on code maintenance, so there is some downside. But generally, I've found going above and beyond to support smooth upgrades for users to be well worth it in the long run. Thanks again, -John On Fri, Jan 6, 2023, at 05:49, Gantigmaa Selenge wrote: > Hi everyone, > > I would like to start a discussion on the MirrorMaker update that > proposes > replacing the deprecated alterConfigs API with the > incrementalAlterConfigs > API for syncing topic configurations.
