andreschaffer/event-sourcing-cqrs-examples
This is a Java-based banking service application that manages clients and their accounts through a REST API. It implements an event-sourcing architecture where domain models for accounts and clients emit immutable events to an in-memory event store. The system processes these events via listeners to update read-model projections, allowing the service to serve account balances and transaction histories. Core capabilities include enrolling clients, opening accounts, and processing deposits and withdrawals with optimistic locking for concurrency control.
