For Developers
Database optimization should begin with measurement. Monitor query duration, rows read, CPU, memory, and lock waits. Identify slow queries and inspect execution plans to see whether indexes are used.
Indexes improve reads but consume storage and slow writes. Create them for filtering, joins, and sorting, paying attention to composite column order. Avoid fetching unused columns, use pagination, avoid expressions that disable indexes, maintain statistics, and monitor performance as data grows.
