neos/Neos.EventSourcing

This system is an event sourcing framework that manages domain events, persistence, and projections. It provides infrastructure for recording and replaying events, managing state through projections, and handling asynchronous processing via job queues. The codebase replaces a previous CQRS implementation with a more robust event store and listener system.

The project removed the entire legacy CQRS infrastructure, including command, query, and event bus components. In their place, the codebase was refactored into a new event-sourcing architecture featuring a flexible EventStore, projection management, and CLI tools for state migration.

This period focused on establishing the core infrastructure for event-sourced aggregates, including abstract base classes and exception handling. It also introduced robust serialization mechanisms for value objects and proxied classes, alongside comprehensive unit and functional tests to verify these new components.

This period focused on implementing the core event sourcing architecture, introducing the Event Publisher subsystem for asynchronous processing and event mapping. Significant effort was also dedicated to comprehensive unit testing for the new components, including the InMemoryStreamIterator and various event handling classes.
