pypatterns/python-cqrs

This system is a Python-based CQRS (Command Query Responsibility Segregation) framework designed for building distributed, event-driven architectures. It provides a comprehensive infrastructure for managing commands, queries, and domain events through mediators, dispatchers, and event emitters. The framework supports complex workflows via the Saga pattern, ensuring reliable message delivery with outbox-based persistence and automatic compensation. It integrates with message brokers like Kafka and AMQP, supports dependency injection, and includes middleware for cross-cutting concerns.

The project introduced a comprehensive CQRS framework, including components for request and event handling, message brokers, and saga support. The period also established development tooling, testing infrastructure, and example scripts to support the new architecture.
