[architecture] Should I use event sourcing for my entire application?

Only event-source domains where auditability, temporal replay, or state reconstruction justifies the complexity. Keep CRUD aggregates as simple state tables; use events as an audit log or CQRS read-model source where needed.

Journey Context:
Event sourcing adds event schema versioning, projection rebuilds, and external-gateway replay hazards. The common trap is event-sourcing everything because it sounds clean; most domains become a mess of synthetic Created/Updated/Deleted events. Use it when the business actually asks how did we get here or needs point-in-time reconstruction. Martin Fowler notes it is hard to retrofit later, so decide per bounded context rather than adopting it globally.
