Lineage

This page is the authoritative reference for lineage in Matia. Lineage shows how data flows from sources through the warehouse and transformations to the BI layer or reverse ETL destinations.

What Lineage Includes

• Warehouse metadata: After your warehouse is connected, Matia uses its metadata as the backbone of the graph (tables, schemas, databases).
• Matia integrations: ETL and reverse ETL integrations appear as nodes. You see data flowing into the warehouse from ETL sources and out to destinations via reverse ETL. Both are treated as integration nodes in the graph.
• dbt: With dbt Core or dbt Cloud connected, Matia parses SQL and builds lineage between warehouse tables and dbt models. You see how dbt models depend on each other and on warehouse tables.
• BI layer: Where supported, lineage extends to the BI layer (e.g. Tableau, Metabase) so you can see which warehouse or dbt columns feed which reports or dashboards.

Together this gives a single view of data flow across pipelines, transformations, and analytics.

Where to View Lineage

Lineage is available from a table’s catalog page. Open the table (browse the catalog or use search), then open the Lineage tab. The home node is that table. Use the canvas controls (e.g. arrows) to navigate upstream and downstream and expand the graph.

Node Types

• Tables: Warehouse tables. Click a table node to open a sidebar with metadata, monitors, and integrations.
• dbt models: Represent transformations connecting tables. Click to see model metadata and SQL.
• Matia integrations: ETL or reverse ETL pipelines. Click to see integration metadata, recent syncs, and a link to the integration details page.

Using Lineage

• Root cause: When a monitor alerts or data is wrong, trace upstream to find the source or transformation that caused it.
• Impact: Before changing or retiring a table, trace downstream to see which dbt models, BI assets, or integrations depend on it.
• Context: Use the sidebar on each node to see owners, tags, sync status, and run history.
