Pipeline Control

The Pipeline provides a comprehensive overview of the enrichment workflow applied to the table, tracking all the logs done by the user, such as get table, modifications, reconciliations, extensions, cell entity link propagation, and save table. It automatically reconstructs the entire operational history—or "timeline"—by ordering actions chronologically based on their timestamps.

Simply open the Pipeline control panel, located in the top-right of the SubToolbar, to visualize the enrichment operations in two distinct ways:

• Sequential List: A chronological log of all performed actions.
• Tree View (DAG): A Directed Acyclic Graph (DAG) representation that maps the dependencies between operations.

This visualization allows you to understand how different operations relate to one another—for example, how an extension might depend on a previous reconciliation.

Operational Control and Dependencies

The system manages dependencies to maintain data consistency offering advanced management capabilities that go beyond simple undo/redo actions:

• Safe Deletion: When no dependencies are violated.
• Cascading Deletion: When deleting an operation that others depend on, all the dependent operations as well will be removed as well.

Operation	When can I delete an operation?
Reconciliation	Only if the result is not used by any Extension operation, or when Reconciliations done in sequence on the same column.
Extension	Only if no Modification or Reconciliation operation is done using the column created by the operation or as context of another Extension
Modification	Only if the result or the newly created column is not used by any Reconciliation operation or used as support context from other operations

NOTE

Modification is considered a "destructive" operation because it directly edits cell values. Reversing them may require careful handling of the operation history: by ignoring the changes or store previous value of the column in the log (heavier).

Dependencies (To/From)	Reconciliation	Extension	Modification	Annotation Propagation
Reconciliation	❌	✅¹	✅¹	❌
Extension	✅	✅²	✅²	✅
Modification	❌	✅¹	✅¹	❌
Annotation Propagation	✅	❌	❌	❌

¹: Includes Normal and Context dependencies. ²: Includes Context dependencies.

NOTE

While most enrichment operations are tracked, some actions—such as manual column deletion or automatic annotations—are not currently part of the Pipeline history.
