May 2025 monthly summary: Focused on reliability, performance, and accessibility improvements across VictoriaMetrics repos. Delivered two features to strengthen data ingestion stability and throughput, and expanded Chinese documentation for MCP integration. Key outcomes include: 1) Ingestion Protocols Testing and Data Import Coverage: added apptest package, data import methods for Graphite/OpenTSDB, and extended apptest.Client to support TCP writes, reducing release risk and increasing ingestion reliability. 2) Dynamic Dial Limit Tuning in vmselect: implemented dynamic adjustment of the concurrent dial limit based on -search.maxConcurrentRequests to speed up connection establishment and improve ingestion and query throughput. 3) MCP Integration Documentation (Chinese): added Simplified and Traditional Chinese docs to improve accessibility. Overall impact: improved reliability, throughput, and accessibility, enabling faster value realization for users. Technologies/skills demonstrated: Go, test scaffolding, performance tuning, and technical writing for localization.

Monthly work summary for 2025-04 focused on enhancing the VictoriaMetrics VMagent and improving release notes management. Key delivered changes: - VMagent: Introduced consistent hashing-based sharding for remote write, replacing round-robin to improve data distribution and resilience when destinations are added/removed; updated logic to count dropped metrics accurately under sharding. - Changelog maintenance: Fixed an update note and sorted upcoming changelog entries alphabetically to ensure release notes accuracy and readability. Impact and context: - No critical customer-facing bugs were reported this month; main value delivered is increased reliability and scalability of the metrics pipeline and improved maintenance workflow for release notes.
