schneisn/ddd-cqrs-es

This is a Java-based microservice implementing a Domain-Driven Design architecture using CQRS and Event Sourcing. It manages user lifecycle operations, persisting state changes as versioned domain events in a PostgreSQL-backed event store. The system asynchronously processes these events to update MongoDB read models and trigger Kafka-based notifications, supported by a command bus and distributed locking mechanisms.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 31 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit a610c75141 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
