Episode notes
Event Sourcing Preserves History
- Event sourcing stores all events leading to the current state instead of just the current state itself.
- This allows replaying events to reconstruct past states, preserving full system history.
Database Normalization Trade-offs
- Normalized databases were designed to save disk space when storage was costly.
- Today, disk space is cheap; CPU, memory, and bandwidth are more critical resources.
Joins Limit Scalability
- Normalized databases require costly joins to reconstruct data from multiple tables.
- These joins limit scalability and introduce concurrency challenges handled by transactions.
