Viewing Data Asset Details
The Asset Details page comprises four tabs (Overview, Schema, Policy, and Audit).
To access the Asset Details page, click an asset in the Data Catalog Search page. This brings you to the Overview tab, the first of the four tabs that form the Asset Details page.
Overview: Displays an overview for the data asset.
- Table properties: Number of rows, number of columns, number of partitions, owner, and tags
- Lineage: Shows the chain of custody for the data from relevant metadata repositories such as Apache Atlas. Lineage shows both upstream paths (lineage) into and downstream paths (impact) out of a given asset.
- Schema: Displays the schema of the data asset for structured data (such as Hive tables) from the relevant metadata repositories (such as Atlas).
Policy: The policy view shows security (authorization) policies defined on assets such as those present in Apache Ranger. It includes both resource (physical asset based) as well as classification based policies
Audit: The data asset audit logs page shows the most recent access audits from Apache Ranger.
