Applying Event Sourcing in Python

Compare the Python 'eventsourcing' library with a manual implementation approach based on criteria such as developer experience, persistence options, and maintainability.

Set up the 'eventsourcing' library with a message broker integration for event notification.

Implement aggregates, commands, and events for a sample application using the framework's abstractions.

Configure the framework to use a separate persistence service (e.g., PostgreSQL) for event storage.

Implement projections and read models that are driven by the framework's notification system.

Write unit and integration tests for an event-sourced application using the framework's testing utilities.
