### 🧬 What Makes Series 2 Different?
✅ We show the internal source code from the official GitHub repos of MySQL, PostgreSQL, and MongoDB
✅ Live debugging and instrumentation walkthroughs
✅ You run labs locally, inspect logs, retry events, and simulate failure
✅ We help you trace real crash recovery, log replay, and buffer pool internals
🔧 Dive into Real Source Code • Crash Recovery • Retry Logic • Live Demos
