Any source. Any target. Fast.

Addax is an actively maintained successor to Alibaba's DataX, which has been frozen since 2023 — a fast, versatile, open-source ETL (Extract, Transform, Load) tool supporting over 30 RDBMS and NoSQL data sources. It provides a growing ecosystem of plugins and offers easy-to-follow configuration for data integrations.

简体中文

• Supports 30+ SQL and NoSQL data sources, and easily extendable for more.
• Configurable via simple JSON-based job descriptions.
• Actively maintained with improved architecture and added functionality compared to DataX.
• Docker images for quick deployment.

Detailed instructions on installation, configuration, and usage are available:

• Online Documentation
• GitHub Docs
• Plugin Comparison

Addax is actively maintained. The project is in a mature maintenance phase by design:

• Monthly maintenance releases. A new release ships roughly every month (see Releases), bundling dependency/CVE updates and bug fixes — even when there are no new features to announce.
• Responsive issue triage. Open issues are typically answered and resolved within days, not months.
• Stable by intent. Plugin functionality is deliberately kept stable: we fix bugs and update dependencies rather than chasing feature churn. New data-source plugins are added when there is real community demand — if you need one, open an issue.
• Open to contribution. PRs are reviewed continuously. See CONTRIBUTING.md for how to contribute.

For maintainers, the release process is documented in RELEASING.md.

Addax supports a wide range of database systems and file sources. Below is a selection of supported platforms:

For AI assistants: project-specific knowledge and conventions are documented in SKILL.md. Please read it before working on this repo.

Follow general Java conventions and patterns:

1. Use IntelliJ IDE with Airlift's Code Style
2. Categorize exceptions clearly with AddaxException (e.g., AddaxException(REQUIRE_VALUE, "missing required parameter")).
3. Use the Java 8 Stream API cautiously (avoid in performance-sensitive areas).
4. Avoid ternary operators for non-trivial expressions.
5. Include proper Apache License headers in every file.
