Add process resource metrics
Add process resource metrics (such asUserTimeMicroseconds,SystemTimeMicroseconds,RealTimeMicroseconds) to part_log profile events forMergePartsentries. #83460 (Vladimir Cherkasov).
Why it matters
This feature enhances monitoring and diagnostics by providing granular timing information on the system and user CPU time consumed during part merge operations. It helps users analyze performance and resource usage more precisely during merges.How to use it
The additional resource metrics automatically appear in thepart_log for entries where event_type is MergeParts. Users can query the part_log system table as usual to review these new timing columns without requiring extra configuration.
