I think making `ReplicaPlacer` configurable is a good strategy. We can integrate KIP-1194: Optimize Replica Assignment for Broker Load Balance in Uneven Rack Configurations into it, allowing users to choose between the current `StripedReplicaPlacer` approach or the `WeightedReplicaPlacer` mentioned in KIP-1194.
Perhaps the replica reassignment algorithm could also be made configurable, enabling users to select solutions like KIP-1151: Minimal movement replica balancing algorithm through configuration. 黃竣陽 <s7133...@gmail.com> 于 2025年8月6日周三 下午8:03写道： > Hello chia, > > Thanks for the reply, > > chia_00, chia_01, chia_02: I have updated the KIP based on your comments. > > Best Regards, > Jiunn-Yang > > > Chia-Ping Tsai <chia7...@gmail.com> 於 2025年8月6日 凌晨12:18 寫道： > > > > hi Jiunn-Yang > > > > chia_00: > > > > Could you please add more alternatives?
