During a two-month period, Zbarsky contributed to the get-convex/convex-backend repository by building tools to improve storage diagnostics and search metrics. He developed a lightweight in-memory storage testing utility in Rust, enabling efficient validation of object size retrieval without requiring a full backend implementation. Zbarsky also enhanced the db-info command to report index sizes, providing better visibility into storage footprint and supporting capacity planning. In the following month, he introduced search index metrics instrumentation, standardizing per-index size reporting and metrics tracking using asynchronous programming. These contributions deepened observability and streamlined testing, reflecting a focused approach to backend development challenges.
January 2026 monthly summary for get-convex/convex-backend focused on improving observability and metrics for search operations. Delivered Search Index Metrics Instrumentation that introduces a new structure for reporting per-index sizes in the searchlight module, enabling deeper visibility into index health and space usage. Added SearchIndexMetricLabels to a set of core functions to standardize detailed metrics reporting across the search path. The work is encapsulated in the commit 6ee232ab462fc01b758b56784cf32eb60652ecda ("[searchlight] Report per-index sizes (#44906)"), tying instrumentation changes to a concrete release signal.
