SQL Performance Tuning Guide 📊

Key Strategies for SQL Performance Tuning

1. Optimize Queries

   • Use EXPLAIN to analyze query execution plans.
   • Avoid SELECT * and specify only necessary columns.
   • 

2. Use Indexes Wisely

   • Create indexes on frequently queried columns.
   • Balance index creation with write performance considerations.
   • 

3. Database Configuration

   • Tune memory allocation and connection pooling settings.
   • Regularly update statistics for query optimizers.
   • 

Best Practices

• Batch operations to reduce round-trips between client and server.
• Normalize vs. denormalize based on read/write patterns.
• Monitor slow queries using tools like pg_stat_statements (PostgreSQL) or SHOW PROFILE (MySQL).
