## What lineage does Atlan extract from Matillion?

Atlan uses Matillion's metadata API to generate lineage associated with [Matillion connectors](https://www.matillion.com/connectors). This is particularly useful for creating lineage between different tools.

Due to limitations in metadata provisioning at source, Atlan currently only supports lineage for data transformations between Snowflake tables as both source and destination. The related Matillion processes neither have asset profiles nor are they discoverable. Atlan recommends upgrading to the latest version of [Matillion ETL](https://docs.matillion.com/metl/docs/release-notes-index/) to allow for enhanced metadata provisioning.

:::warning

The assets involved in lineage (tables, columns, and so on) must already be [crawled by Atlan](https://docs.atlan.com/llms/connectors/matillion/what-lineage-does-atlan-extract-from-matillion/llms.txt) before running the [Matillion package](https://docs.atlan.com/llms/connectors/matillion/crawl-matillion/llms.txt) to enrich them.

:::

Specifically, Atlan will:

- Create lineage between each data asset in Atlan that is associated with a Matillion connector. (For example, between Snowflake tables and columns.)
 - Atlan creates Matillion `Process` objects for each data asset that is replicated. Learn more about [processes](https://docs.atlan.com/llms/catalog/lineage/what-are-processes/llms.txt) here.
