Lineage

Lineage settings control what a user sees the first time they open a lineage graph, before they zoom, expand, or filter it manually. Because lineage graphs can grow very large, these defaults balance two things:
  • Showing enough context
  • Keeping the graph readable and fast to load
Tune them if users on your instance routinely have to expand the graph manually to see the hops or layer they care about. Purpose and Benefits
  • Purpose: Set the default upstream/downstream depth, lineage layer, and pipeline view mode.
  • Benefits: Every lineage graph opens already balanced between showing enough context and staying readable and fast to load.
The Lineage tab on an asset’s details page has its own Lineage Config control (Settings icon). Upstream Depth, Downstream Depth, and Nodes Per Layer only change your current view and reset to the defaults configured on this page. Show temporary tables is remembered for your user in this browser. Change the settings on this page instead if you want new defaults to apply for every user, every time.

How to Configure

To configure the default Lineage view, follow the steps below:
  1. Navigate to Settings > Preferences > Lineage. Lineage settings
  2. Set the following fields:
    • Upstream Depth: Number of upstream hops shown by default when opening a lineage graph, to identify parent-level sources. Default: 2 (range 1–5).
    • Downstream Depth: Number of downstream hops shown by default when opening a lineage graph, to identify child-level targets. Default: 2 (range 1–5).
    • Lineage Layer: Which layer of data relationships loads by default:
      • Entity Lineage: Higher-level connections between entities (default).
      • Column Level Lineage: Relationships between individual columns.
      • Data Observability: Data quality and monitoring insights layered onto the graph.
    • Pipeline View Mode: How pipelines render on the lineage graph:
      • Node: Pipelines appear as their own nodes, showing more detail on data flow through each pipeline (default).
      • Edge: Pipelines appear as direct connections between nodes, for a simpler view.

  3. Click Save.

Show Temporary Tables

The Lineage Config dialog on an asset’s Lineage tab includes a Show temporary tables switch. Each user controls it for their own view.
  • Default: On. The graph draws the temporary tables a query wrote through between two tables.
  • When off: The graph joins the two tables with a direct edge instead.
  • Scope: Available on an asset’s Lineage tab only, not on Impact Analysis.
  • Apply: Click Ok to apply the change, or Cancel to close the dialog. The graph redraws without reloading.
  • Missing tables: An edge whose end table is missing no longer draws a dead-end chain of temporary tables.
