> What does Atlan crawl from DataStax Enterprise?

Atlan integrates with DataStax Enterprise to crawl and map various asset types, helping you discover and understand your distributed data. This page outlines the DataStax Enterprise components that Atlan supports and how their properties are mapped.

## Lineage support

Atlan also supports the following lineage:

- Asset-level lineage for **Tables** and **Materialised Views**.
- Column-level lineage for **Tables** and **Materialised Views**.

## Assets

Atlan crawls and maps the following assets and properties from DataStax Enterprise Cassandra.

## Keyspaces

Atlan maps keyspaces from DataStax Enterprise Cassandra to its `Keyspace` asset type.
