Design comprehensive indexing strategies to improve query performance, reduce lock contention, and maintain data integrity. Covers index types, design patterns, and maintenance procedures.

❌ Don't create too many indexes (write performance impact) ❌ Don't create indexes without testing first ❌ Don't ignore index size and storage impact ❌ Don't forget to update table statistics after bulk operations ❌ Don't create duplicate indexes

✅ DO create indexes on foreign keys ✅ DO test index impact on INSERT/UPDATE performance ✅ DO use covering indexes for common queries ✅ DO drop unused indexes regularly ✅ DO monitor index fragmentation

設計和實施數據庫索引策略。在 PostgreSQL 和 MySQL 中創建索引、選擇索引類型或優化索引性能時使用。 來源：aj-geddes/useful-ai-prompts。
