July 2025 performance summary for crossoverJie/starrocks focused on reliability and telemetry accuracy for vector index caching. Implemented a bug fix to Vector Index Metrics Accuracy by correctly setting hit_count and computing dynamic_hit_count/dynamic_lookup_count to reflect the actual cache hit ratio. This change, committed as [BugFix] set hit_count in vector index metrics (#61102) (2dbfc1d516dc534b7709df85373d16e3e1374f5e), improves telemetry fidelity and supports data-driven caching optimizations. No new user-facing features this month; primary business value comes from more reliable metrics, enabling faster diagnosis and better resource allocation. Collaboration with the StarRocks repository team to ensure consistency across metrics reporting.
