What does Atlan crawl from DataStax Enterprise?

🧪 Preview feature! This feature is currently in an experimental phase, and its functionality may change before the final release. We’d love your feedback to refine it. To request access to the DataStax Enterprise connector in your Metadata Marketplace, Atlan Secure Agent Installer, and Secure Agent documentation, create a ticket with Atlan Support.

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.
