Database Performance Excellence

Database optimization is crucial for scalable web applications. Poor database performance can create bottlenecks that affect the entire user experience, regardless of how well-optimized your frontend code is.

Query Optimization Techniques

Analyze and optimize slow queries using EXPLAIN plans. Avoid N+1 queries, implement proper joins, and use appropriate WHERE clauses with indexed columns.

Indexing Strategies

Create strategic indexes on frequently queried columns, but balance between read and write performance. Composite indexes can significantly improve complex query performance.

Connection Pooling

Implement connection pooling to manage database connections efficiently. This reduces connection overhead and improves application scalability under high load.

Caching Layers

Implement Redis or Memcached for frequently accessed data. Cache query results, session data, and computed values to reduce database load.

Database Schema Design

Design normalized schemas to eliminate data redundancy while considering denormalization for specific performance-critical use cases.
