Add new edges, remove existing ones, and link individual columns to build a complete picture of how your data flows. You can edit both table-level and column-level lineage manually — useful for capturing relationships that ingestion doesn't automatically detect. ## Edit a Lineage Build lineage by connecting source and destination nodes in the editor. ### Step 1: Open the Lineage Editor Navigate to the data asset you want to use as the starting point. 1. Go to your database service and open a table. 2. On the table details page, click the **Lineage** tab. 3. Click the **Edit** icon to enable the lineage editor. Data Asset: Lineage Tab ### Step 2: Connect a Destination Asset Select the data asset you want to link as a downstream node. 1. Choose the type of asset to connect — table, topic, dashboard, ML model, container, or pipeline. 2. Search for and select the specific asset. 3. Draw an edge between the two assets to create the lineage connection. Link the Table to the Dashboard to Add Lineage Manually ### Step 3: Add Column-Level Lineage Expand a table node to link individual columns and trace field-level dependencies. 1. Click a table node to expand it and reveal its columns. 2. Use the column anchor points to draw connections between matching columns across assets.
