Progressive expansion mode for the technical lineage graph (in preview)

Important This feature is available only in the latest technical lineage viewer UI.

Progressive expansion mode introduces a streamlined approach to explore the technical lineage graph. When you open a technical lineage graph in this mode, lineage is revealed incrementally as you expand upstream or downstream dependencies.

This feature provides:

Faster initial load times for complex lineage paths
A cleaner starting point for lineage exploration
Reduced visual complexity when working with large technical lineage graph

Progressive expansion mode is disabled by default. When it is enabled, the technical lineage graph opens with only the selected asset displayed as a single node. You can then expand or collapse lineage connections directly from the graph:

Expand a node:
Boundary nodes display an expansion button (). Click the button, or use Tab to move focus to it and press Enter or Space, to load the next level of upstream or downstream connections.

A boundary node is a data object at the edge of the current graph, with lineage displayed on only one side. Additional lineage is available on the other side. Nodes with lineage displayed on both sides are considered fully connected within the current graph and do not have an expansion button. To load more lineage, expand a boundary node at the edge of the graph.
Collapse a node:
Expanded nodes display a collapse button (). Click the button to hide its connections and simplify the view.
Explore incrementally:
Expand only the nodes relevant to your analysis to progressively load sections of the lineage graph as needed.

Note Column-level and table-level lineage are independent. Use the View Type drop-down list in the Display options pane to switch between views: select Attributes to view column-level lineage, and Objects or Transformations to view table-level lineage. The expansion button appears on boundary columns in column-level lineage and on boundary tables in table-level lineage. If a column does not display an expansion button, switch to a table-level view to check whether the corresponding table has additional lineage to expand.

Enable progressive expansion mode

To load lineage incrementally when you open a technical lineage graph, enable the Progressive expansion mode toggle on the Technical lineage settings page in Collibra settings. To load the full technical lineage graph again, disable the toggle.
