enhance: Implement dynamic interval updates for ticker components ( #43865 )
...
issue: #43858
Enable dynamic configuration updates for ticker intervals without
restart. This enhancement allows runtime configuration changes to take
effect immediately for better operational flexibility.
Changes include:
- Apply "drain+Reset only when interval changed" pattern across all
ticker components to preserve existing timing phases
- Fix goroutine variable capture issue in CheckerController.Start()
- Remove unnecessary ticker.Stop() in manual trigger paths
- Add dynamic interval checking in QueryCoordV2 components:
* checkers/controller.go: Various checker intervals
* dist/dist_handler.go: DistPullInterval, CheckExecutedFlagInterval
* session/cluster.go: CheckNodeSessionInterval
* server.go: CheckAutoBalanceConfigInterval
* observers/target_observer.go: UpdateNextTargetInterval
* observers/collection_observer.go: CollectionObserverInterval
- Add dynamic interval checking in QueryNodeV2 components:
* segments/disk_usage_fetcher.go: DiskSizeFetchInterval
- Ensure thread safety by performing all ticker operations in same
goroutine with proper drain before Reset to avoid spurious triggers
