🛠️ Getting Started

Addax can be quickly installed and used via Docker, installation scripts, or compiled from source.

1. Use docker image

Pull the prebuilt Docker image and run a test job:

docker pull quay.io/wgzhao/addax:latest
docker run -ti --rm --name addax \
  quay.io/wgzhao/addax:latest \
  /opt/addax/bin/addax.sh /opt/addax/job/job.json

A lightweight -lite image is also available: Learn more.

2. Use installation script

Install Addax with a single command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/wgzhao/Addax/master/install.sh)"

Installation paths: /usr/local (macOS), /opt/addax/ (Linux).

3. Compile and Package from Source

For developers targeting custom-builds, compile and package Addax locally:

git clone https://github.com/wgzhao/addax.git addax
cd addax
mvn clean package
mvn package assembly:single

The compiled binary will be in target/datax/addax-<version>.

Code Style Guidelines

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.

Refer to our Programming Guidelines for commit message formats.
