Complete MySQL Mastery
Roadmap.
From relational fundamentals to dissecting the InnoDB storage engine. This 8-week roadmap covers the "Why" and "How" of production-grade database engineering.
The Curriculum
PHASE 1: Fundamentals
Master the relational model, understand proper data typing (BIGINT vs INT), and design your first production schema.
PHASE 2: Intermediate Queries
Deep dive into complex Joins, Subqueries vs CTEs, and Aggregations (GROUP BY & HAVING).
PHASE 3: Performance Tuning
Demystify B-Tree Indexing. Understand Clustered vs Non-Clustered Indexes, Double Lookups, and reading EXPLAIN plans.
PHASE 4: Transactions & Safety
Explore ACID properties, Isolation Levels (Read Committed vs Repeatable Read), and Row-Level vs Table-Level locking.
PHASE 5: Advanced Analytics
Master Window Functions. Use OVER(), PARTITION BY, RANK(), and LAG() for deep analytical insights.
PHASE 6: Query Optimization
Optimize N+1 problems, rewrite correlated subqueries, avoid Deep Pagination, and enforce SARGability.
PHASE 7: InnoDB Architecture
Look under the hood at the Buffer Pool, Write-Ahead Logs (WAL), Redo/Undo logs, and Page Structures.
PHASE 8: Replication & HA
Implement Master-Slave replication, understand the Binlog, and handle Failover strategies for Five Nines availability.
PHASE 9: Sharding & Scaling
When vertical scaling fails. Learn Horizontal Partitioning, Shard Key selection, and Consistent Hashing.
PHASE 10: Security & Operations
Role-Based Access Control, at-rest vs in-transit encryption, and Disaster Recovery (PITR).
