Index Strategies
Proper indexing is the #1 performance lever.
SQL
| 1 | -- Composite index for common query patterns |
| 2 | CREATE INDEX idx_posts_user_created |
| 3 | ON posts(user_id, created_at DESC); |
| 4 | |
| 5 | -- Partial index for active records only |
| 6 | CREATE INDEX idx_active_users |
| 7 | ON users(email) |
| 8 | WHERE deleted_at IS NULL; |
Query Optimization
Use EXPLAIN ANALYZE to understand query plans.
