mjsax opened a new pull request, #22748: URL: https://github.com/apache/kafka/pull/22748
Replace the streams-heartbeat bumpGroupEpoch boolean with an AssignmentUpdate enum (NONE/RECOMPUTE/REFINE). RECOMPUTE keeps today's behavior (re-run the assignor for a new final target). REFINE only advances the assignment epoch of the unchanged final target via the target-assignment metadata record, without re-running the assignor, so members re-reconcile toward the next intermediate (warm-up) step. A REFINE bump is triggered by hasHotWarmupTask(): a caught-up warm-up (lag within acceptable.recovery.lag). Each refinement step needs its own assignment epoch because members only pick up a changed assignment when the epoch advances, and a new assignment epoch requires a group-epoch bump. -- This is an automated message from the Apache Git Service.
