Database Optimization Strategies

A slow database often means a slow application. Optimizing your database layer is crucial for user experience.

Indexing Strategies

Indexes are the single most effective way to improve read performance.

• B-Tree Indexes: Good for range queries and equality checks.
• Hash Indexes: Extremely fast for exact lookups but don’t support ranges.

Query Optimization

Avoid SELECT *. Always specify the columns you need. Use EXPLAIN ANALYZE to understand how your database executes a query.

Normalization vs. Denormalization

While normalization reduces redundancy, denormalization can speed up read-heavy workloads by avoiding complex joins.

Conclusion

Database optimization is an ongoing process. Regular monitoring and profiling are key to maintaining a healthy system.
