[VOTE] PIP-460: Scalable Topics (Topics v5) 🚀 Voting thread: https://lists.apache.org/thread/jd9kklo3qlbmt2cxg1s7oynof14gmsn4 PIP-460 introduces a new topic type that uses range-based routing instead of modulo hashing, enabling transparent splitting and merging of streams without breaking key ordering or requiring downtime. This is a parent PIP that establishes the motivation, goals, and key challenges; detailed design for each area (segment model, producer protocol, consumer controller, message entry format, split/merge mechanics, consumer APIs, geo-replication, and more) will follow in dedicated sub-PIPs.
