and same rate All rate-limiting plugin instance syncs with the same plugin config, that is the very first config got hit by a request, and they all sync with the same rate. Even a config update won't change the DB to be synced. Fix KAG-2904 Co-authored-by: samugi <samuele@konghq.com>

All rate-limiting plugin instance syncs with the same plugin config, that is the very first config got hit by a request, and they all sync with the same rate. Even a config update won't change the DB to be synced. The timer will sync not just the same instance's counters but all counters in the same DB. This is a compromise given the emergency and we prefer simplicity over correctness for this behavior. Full changelog - The counter table is split with DB; - Timers are created when a request hits; - The sync_rate is guaranteed with limited running timers and timer delay - Cover the case in the integration test by "with_sync_rate" Fix KAG-2904 Co-authored-by: samugi <samuele@konghq.com>
