Report #98255

[architecture] Event sourcing chosen as the default architecture and becomes a complexity trap

Start with a simple relational model; only adopt event sourcing when you genuinely need audit history as a first-class concern, temporal queries, or pub/sub decoupling, and when you can afford idempotent projections and schema evolution of event payloads.

Journey Context:
Event sourcing is powerful for audit, replay, and complex domains, but it introduces dual-write risks \(event log vs projections\), eventual consistency across read models, versioning of immutable event schemas, and operational tooling that most teams underestimate. A common failure mode is using it for CRUD apps because it sounds clean. If you do adopt it, avoid event-sourcing everything; boundary aggregates independently and keep projections simple and rebuildable.
