# DataHub Features
|
|
|
|
DataHub is made up of a [generic backend](what/gma.md) and a [React-based UI](../datahub-web-react/README.md).
|
|
Original DataHub [blog post](https://engineering.linkedin.com/blog/2019/data-hub) talks about the design extensively and mentions some of the features of DataHub.
|
|
Our open sourcing [blog post](https://engineering.linkedin.com/blog/2020/open-sourcing-datahub--linkedins-metadata-search-and-discovery-p) 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](architecture/metadata-ingestion.md).
|
|
|
|
We also have a [Python-based ingestion framework](../metadata-ingestion/README.md) 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](what/mxe.md) format, and the framework will help ingest metadata to DataHub.
