Episode notes
Events As The Source Of Truth
- Event sourcing prevents data loss by storing immutable records of what happened instead of overwriting state.
- That ledger-like approach becomes the definitive tiebreaker for system truth and design decisions.
Additive State Simplifies Complexity
- Event sourcing enforces additive-only state, immutable records, and pure functions by default.
- Those defaults reduce accidental information loss and hidden complexity from CRUD updates.
Use Dynamic Consistency Boundaries
- Dynamic consistency boundaries let you avoid replaying full histories for some actions and only use needed context.
- This reduces coupling and allows simpler commands like unconditional cancels when appropriate.
