Overview

Lineage allows you to visualize the complete lifecycle of your data, from its origin to its destination.

A fully-fledged lineage can notably help your team with:

• Root cause analysis: identify where an issue might have originated from by looking at the upstream dependencies of your asset.
• Business impact assessment: spot which teams might be impacted by an issue by looking at downstream dependencies of your asset.
• Knowledge sharing: make your data lifecycle easy to understand for any new joiner on the team.
• Monitoring coverage: ensure critical assets that feed a lot of other assets are being properly monitored.

Navigate the Lineage

To access the lineage view of an asset:

1. Click the Data Catalog entry on the sidebar of your Sifflet application
2. Search for your asset of interest
3. Click its card on the Data Catalog results list
4. Once on the asset page, go to the Lineage tab.

Lineage node tiles contain details about the asset's:

• Technology
• Type
• Fully qualified name: currently available for Tables & Views assets and declared assets
