Getting Started with Lineage
Lineage lets you trace how data flows between containers and fields across your datastores, so you can understand where data quality issues start and where they spread.
In this section you will learn how lineage works, how connections are created and managed, and how to navigate the graph. Any user with the Manager role can add or remove connections, while Member users can view the graph.
Tip
Lineage is delivered as an add-on. If the Lineage tab is not visible on your containers, an Admin can enable it from the Add-ons side panel.
Deep Dive
-
Introduction
What lineage is, why it is worth keeping, and what the rest of this deep dive covers.
-
How It Works
The connection model, the two levels of granularity, the rules a connection has to obey, and how to find the containers that have one.
-
Lineage Sources
The four categories a connection can come from, and how each is created, updated, and removed.
-
Reading the Graph
Direction, nodes, assets outside Qualytics, where a connection came from, and expanding the graph.
-
Field-level Lineage
Expanding field lists, field metadata (type, status, anomaly counts), and the focal field workflow.
-
Examples
Enrolling a warehouse, a medallion pipeline across datastores, a remediation table, and a hop only a person can record.
-
Best Practices
Which source to lean on, how to run collection, and how to keep a graph you can trust.
-
Permissions
The add-on gate, what each role can do, and why a deleted connection can come back.
How-tos
-
Add an Upstream Connection
Record that another container or field feeds the one you are on, with the field reference for the panel.
-
Add a Downstream Connection
Record that the container you are on feeds another one, with the field reference for the panel.
-
Delete a Connection
Remove a connection, and what that does and does not change.
-
Expand the Graph
Load one more step from a node, or follow a whole side of the graph to its end.
-
Focus on a Container or Field
Dim everything that is not connected to the container or field you picked.
-
View Anomalies
Open the Anomalies side panel from a container or field directly on the graph.
