Add Setting for Async Inserts Deduplication Cache Update Timing and Deprecate Old Interval Setting
Add a setting forasync inserts deduplication cache- how long we wait for cache update. Deprecate settingasync_block_ids_cache_min_update_interval_ms. Now cache is updated only in case of conflicts. #57743 (alesapin).
Why it matters
This feature improves the efficiency and correctness of async inserts deduplication by updating the cache only when necessary—during conflicts—thereby reducing unnecessary cache refreshes and improving performance.How to use it
Users can configure the new setting to specify how long the async inserts deduplication cache waits before updating. The previous settingasync_block_ids_cache_min_update_interval_ms is deprecated and should no longer be used.
