DataHub Features

DataHub is made up of a generic backend and a React-based UI. Original DataHub blog post talks about the design extensively and mentions some of the features of DataHub. Our open sourcing blog post also provides a comparison of some features between LinkedIn production DataHub vs open source DataHub. Below is a list of the latest features that are available in DataHub, as well as ones that will soon become available.

Metadata Sources#

There's a basic, Java-oriented overview of metadata ingestion.

We also have a Python-based ingestion framework which supports the following sources:

  • Hive
  • Kafka
  • RDBMS (MySQL, Oracle, Postgres, MS SQL, etc)
  • Data warehouse (Snowflake, BigQuery, etc)
  • LDAP

That ingestion framework is extensible, so you can easily create new sources of metadata. You just need to transform the metadata into our standard MCE format, and the framework will help ingest metadata to DataHub.
