Lineage

Navigate the lineage graph to understand how your data flows between tables, dashboards, and BI tool models.

What Is It?​

Where Does Data Come From? Does a Dashboard Use This Data?​

Lineage answers many questions. Among them:

  • You have found an interesting dashboard, but you want to make sure it uses the right source of data
  • You know a table has the information you need. Does a dashboard already provide analysis for it?

Asset Level vs Field Level​

When we talk about asset-level lineage, we want to understand how tables, dashboards, and BI tool models are linked to one another.

For more specific questions, field-level lineage helps. You can understand data flows at the column level.

Sources​

Ever wondered which tables are the ancestors of a table or dashboard?

Sources travels up the lineage to the first ancestral elements.

Parents and Children​

Find out which tables and dashboards are directly related to your tables upstream and downstream.

By clicking the "Export Children" button, you can also export and download all lineage children in a CSV file.

Lineage Graph​

Lineage graphs are not only nice to look at, they are also useful.

In Catalog, we want you to focus on the most useful use cases and keep graphs as clear as possible.

You start small, then expand to get the information you need.

Going Downstream​

You need to make a modification to a table and check the impact? Or check where a table is used?

By clicking "+" on the right of any table in the graph lineage, you will discover assets created from the selected one.

Going Upstream​

You need to troubleshoot a problem in a table? Checking where the data comes from is always a good idea.

Deep dive into the origins of the data by clicking the "+" on the left of a table.

Dashboards and Tables​

Dashboards and tables come from different technologies. Understanding the link between them is not straightforward.

Catalog can help. Full links between tables and dashboards can be established with Graph lineage.

Lineage Graph Refresh​

Every time your data is synchronized into Catalog, the lineage is refreshed. The lineage graph displayed in Catalog uses data from the last 30 days.

Still seeing some old links in your graph? Try updating the time range below so you can see lineage computed on less than 30 days and see the impact of your recent SQL changes.
