EventSauce4j\n\nA lightweight, **event sourcing** toolkit for Java + Spring, inspired by (and conceptually aligned with) [EventSauce](https://eventsauce.io/).  \nIt provides clean building blocks for **domain events**, **message repositories**, **dispatching**, **outbox**, with a persistence module.\n\n\u003e If you know EventSauce in PHP, you should feel at home: the vocabulary, responsibilities, and flow are intentionally adapted to Java idioms.\n\n[![Build Status](https://github.com/omidp/EventSauce4j/actions/workflows/ci.yml/badge.svg)](https://github.com/omidp/EventSauce4j/actions/workflows/ci.yml)\n\n---\n\n## Table of Contents\n\n- [Features](#features)\n- [Requirements](#requirements)\n- [License](#license)\n- [Roadmap](#roadmap)\n- [Build](#build)\n- [Usage](#usage)\n\n---\n\n## Features\n\n- **Familiar EventSauce model** (Domain Events, Message Repositories/Decorators, Dispatchers).\n- **Outbox** support for reliable, exactly-once external publishing.\n- **Pluggable serialization** (Jackson by default).\n\n---\n\n## Requirements\n\n- **Java**: 17 or later\n- **Build**: Maven 3.8+\n- **Database**: PostgreSQL 13+ (recommended 14+)\n\n---\n\n## License\nLicensed under the Apache 2.0 License.\n\n---\n\n## Roadmap\n\n- Implement JDBC Outbox pattern.\n- Enhance spring boot configuration.\n- Add idempotency key handling for consumer de-duplication.\n\n---\n\n## Build\n\n```\nmvn clean install\n```\n\n## Usage\n\nFor reference, see the Spring Boot example project:
