Optimize MySQL for high-performance applications.
Learn indexing, query optimization, and configuration.
Indexing Strategies
— B-tree index (default)
CREATE INDEX idx_name ON users(email);
— Composite index
CREATE INDEX idx_composite ON orders(user_id, created_at);
— Full-text index
ALTER TABLE posts ADD FULLTEXT(title, content);
Query Optimization
EXPLAIN SELECT * FROM users WHERE email = ‘test@example.com’;
Configuration Tuning
innodb_buffer_pool_size = 4G
max_connections = 200
query_cache_type = 1
Monitoring
SHOW STATUS LIKE ‘Threads%’;
SHOW PROCESSLIST;
Conclusion
Proper tuning can 10x your database performance!
