Hi all, We've been having discussions on a few different KIPs (KIP-236, KIP-435, etc.) about what the Admin Client replica reassignment API should look like. The current API is really hard to extend and maintain, which is a big source of problems. I think it makes sense to have a KIP that establishes a clean API that we can use and extend going forward, so I posted KIP-455. Take a look. :)
best, Colin
