## What does Atlan crawl from Google Cloud Composer/OpenLineage?

URL: https://docs.atlan.com/apps/connectors/lineage/google-cloud-composer-openlineage/references/what-does-atlan-crawl-from-google-cloud-composer-openlineage

> Atlan maps the following assets and properties from Google Cloud Composer/OpenLineage. Asset lineage support depends on the [list of operators supported by OpenLineage](https://airflow.apache.org/docs/apache-airflow-providers-openlineage/1.6.0/supported_classes.html).

Once you have [integrated Google Cloud Composer/OpenLineage](https://docs.atlan.com/llms/connectors/google-cloud-composer-openlineage/integrate-google-cloud-composer-openlineage/llms.txt), you can [use connector-specific filters](https://docs.atlan.com/llms/catalog/discovery/use-the-filters-menu/llms.txt) for quick asset discovery. The following filters are currently supported:

- Status filter - last run status for an asset
- Duration filter - last run duration for an asset

Atlan maps the following assets and properties from Google Cloud Composer/OpenLineage. Asset lineage support depends on the [list of operators supported by OpenLineage](https://airflow.apache.org/docs/apache-airflow-providers-openlineage/1.6.0/supported_classes.html).
