A Python library for implementing the event sourcing pattern, storing all application state changes as a sequence of immutable events. It provides aggregate and application base classes with pluggable persistence backends such as SQLAlchemy and Django.

Use cases

• build event-sourced applications in Python
• store domain state as a sequence of events
• implement CQRS and domain-driven design patterns
• create an audit log of all state changes
• persist aggregates to a database with SQLAlchemy or Django
• reconstruct application state by replaying events

When to choose

• you need full event sourcing with aggregates in Python
• you want an audit trail or temporal history of state changes
• you are following DDD/CQRS architecture
• you need pluggable persistence backends like SQLAlchemy or Django ORM

When to avoid

• you just need simple CRUD persistence without event history
• your team is unfamiliar with event sourcing concepts
• you need a distributed event streaming platform like Kafka rather than an embedded event store
