[PR] PHOENIX-8005 Make scheduled round-boundary rotation non-coalescible [phoenix]
tkhurana opened a new pull request, #2620:
URL: https://github.com/apache/phoenix/pull/2620
The time-based rotation tick and size/fault rotations shared one rotationRequested CAS gate, so a scheduled boundary tick firing while an on-demand rotation held the gate could be coalesced away, leaving a round boundary without its own .plog file.Make coalescing asymmetric in requestRotation(boolean): on-demand callers still CAS the gate (coalescing into any in-flight rotation, including a scheduled one), while the scheduled tick force-holds the gate with set(true) and always enqueues, so a boundary is never coalesced away. No new synchronization state; LogRotationTask still clears the gate in its finally.Adds testScheduledTickNotCoalescedWhenGateHeld and testOnDemandCoalescesIntoScheduledRotation.
