backend-event-sourcing

What problem does it solve?

It helps teams model complex business processes by recording immutable domain events instead of relying solely on mutable database state, making history, auditing, and recovery easier.

Core Features & Use Cases

• Event Sourcing: Captures domain changes as a time-ordered stream of events to preserve intent and enable replay.
• CQRS: Separates write-side command handling from read-side projections to improve scalability and maintainability.
• Use Case: When building a league management workflow, you can store “match created/updated,” “team registered,” and “points adjusted” as events, then generate read views like standings or audit logs by replaying the event stream.
