📣 DataHub Town Hall is the 4th Thursday at 9am US PT of every month - add it to your calendar!

✨ DataHub Community Highlights:

Introduction​

DataHub is an open-source data catalog for the modern data stack. Read about the architectures of different metadata systems and why DataHub excels here. Also read our LinkedIn Engineering blog post, check out our Strata presentation and watch our Crunch Conference Talk. You should also visit DataHub Architecture to get a better understanding of how DataHub is implemented.

Features & Roadmap​

Check out DataHub's Features & Roadmap.

Demo and Screenshots​

There's a hosted demo environment courtesy of Acryl Data where you can explore DataHub without installing it locally

Quickstart​

Please follow the DataHub Quickstart Guide to get a copy of DataHub up & running locally using Docker. As the guide assumes some basic knowledge of Docker, we'd recommend you to go through the "Hello World" example of A Docker Tutorial for Beginners if Docker is completely foreign to you.

Development​

If you're looking to build & modify datahub please take a look at our Development Guide.

Security Notes​

Multi-Component​

The DataHub project uses a wide range of code which is responsible for build automation, documentation generation, and include both service (i.e. GMS) and client (i.e. ingestion) components. When evaluating security vulnerabilities in upstream dependencies, it is important to consider which component and how it is used in the project. For example, an upstream javascript library may include a Denial of Service (DoS) vulnerability however when used for generating documentation it does not affect the running of DataHub itself and cannot be used to impact DataHub's service. Similarly, python dependencies for ingestion are part of the DataHub client and are not exposed as a service.

Known False Positives​

DataHub's ingestion client does not include credentials in the code repository, python package, or Docker images. Upstream python dependencies may include files that look like credentials and are often misinterpreted as credentials by automated scanners.
