▌
Database Performance Tuning · fcsouza bundle
Diagnose and fix slow databases the way a DBA does — measure first, read the plan, then change one thing. Use this skill whenever a query, endpoint, job or report is slow, times out, or got slower after a deploy; whenever someone asks about indexes (missing, unused, duplicate, composite order, partial, covering, GIN/BRIN), EXPLAIN or query plans, seq scans, N+1 queries, slow pagination, table or index bloat, autovacuum, VACUUM, ANALYZE, stale statistics, connection or lock pileups, high CPU/IO on the database, partitioning, or a migration that locked a table. Also trigger on Portuguese phrasings: 'query lenta', 'consulta lenta', 'banco lento', 'timeout no banco', 'falta índice', 'criar índice', 'travou a tabela', 'lock', 'vacuum', 'plano de execução'. Postgres is the core; MySQL/InnoDB is covered in references/mysql.md. Use it even when the user just says 'this page is slow' and the data comes from a database — the first job of this skill is to find out whether the database is actually the problem.
