Understand Storage Engines: InnoDB (ACID, transactions, foreign keys), MyISAM (fast reads, no transactions), when to use each

Master JSON Functions: JSON_EXTRACT(), JSON_SET(), JSON_ARRAY(), native JSON type (MySQL 5.7+), index with generated columns

Learn Replication: Master-slave replication for read scaling, binary log (binlog), asynchronous/semi-synchronous, GTID for failover

Understand AUTO_INCREMENT: Automatic ID generation, gaps after rollback, per-table counter, LAST_INSERT_ID() to get value

Master Full-Text Search: FULLTEXT indexes (InnoDB/MyISAM), MATCH() AGAINST(), boolean mode, natural language mode

Learn Performance Features: Query cache (deprecated 8.0+), buffer pool tuning, connection pooling, slow query log
