Indexing Strategies

Proper indexing is the foundation of database performance. Learn when to use single-column indexes, composite indexes, and covering indexes for maximum efficiency.

Query Optimization

Analyze and optimize slow queries using EXPLAIN plans. Avoid N+1 queries, use proper JOINs, and leverage database-specific features for better performance.

Connection Pooling

Implement connection pooling to reduce overhead and improve throughput. Configure pool sizes based on your application's needs and database capacity.

Caching Strategies

Use Redis or Memcached for frequently accessed data. Implement cache invalidation strategies and consider read-through and write-through patterns.
