Excerpt

Database Optimization

EXPLAIN Analysis

Always run EXPLAIN ANALYZE before optimizing. Read the output bottom-up.

-- PostgreSQL
EXPLAIN (ANALYZE, BUFFERS, FORMAT TEXT) SELECT ...;

-- MySQL
EXPLAIN ANALYZE SELECT ...;

Key metrics to watch:

Seq Scan on large tables = missing index
Nested Loop with high row count = consider hash/merge join
Sort without index = add index on sort column
Rows estimated vs actual divergence = stale statistics, run ANALYZE

Index Strategies

This is the opening of the README. Read the full README on GitHub.
