KIP-236 — Interruptible Partition Reassignment

Discussion AdminBroker

KIP-236 proposes making partition reassignment interruptible and cancellable via the admin API, allowing in-flight reassignments to be stopped without the dangerous manual ZooKeeper manipulation currently required. A single active reassignment batch cannot be aborted cleanly, and large reassignments can cause sustained cluster performance degradation with no escape valve.
