Performance & tuning
Slow queries are usually a symptom of something specific — a missing index, a bad join order, a query plan the optimizer is getting wrong, a write pattern wrecking the cache. Find the real cause, and fix it. The one that surfaces on the dashboard first might not be it.
- Query plan analysis, statistics tuning, and index design across Oracle, PostgreSQL, and MariaDB
- AWR/Statspack, pg_stat_statements, performance_schema — tracing the real hot paths, not the suspected ones
- Connection pooling, vacuum and maintenance scheduling, partition strategy for tables that have outgrown a single segment
