branch-4.1: [fix](cloud) Skip skewed warmup rowset latency samples #62941#63084
Merged
Conversation
Issue Number: None Problem Summary: CORE-6051 reports negative file_cache_warm_up_rowset_request_to_handle_ samples. The request timestamp is produced on the caller BE while handle and finish timestamps are produced on the target BE, so cross-host wall-clock skew can make the interval negative and bvar drops it. Skip cross-host latency samples when the request timestamp is missing or later than the local timestamp. Release note: Fix file cache warm-up rowset latency metrics to skip invalid cross-BE clock-skew samples.
