Add a Downstream Connection
Record that the container you are looking at, or one of its fields, feeds another one. The connection you add this way is manual, so no data catalog sync and no Qualytics process will ever change or remove it.
Permission Required
You need the Manager role to add a lineage connection. See Lineage Permissions for details.
Field reference
The Add downstream panel has two sections, one for each end of the connection. The node you started from is locked into the upstream section, so the downstream section is the one you fill in.
Two tabs at the top decide what you are connecting, and which fields the panel shows. The first is named after what the datastore holds, so it reads Table on a database and File on a file store.
Connects whole containers.
| Field | Required | Type | Description |
|---|---|---|---|
| Datastore | Select | The datastore holding the downstream container. Any datastore you have access to, including the one you started from. | |
| Container | Select | The downstream container itself. Selectable only after a datastore is chosen. |
Connects one column to another. Both ends need a field, so the locked section gains a field selector of its own.
| Field | Required | Type | Description |
|---|---|---|---|
| Datastore | Select | The datastore holding the downstream container. Any datastore you have access to, including the one you started from. | |
| Container | Select | The downstream container itself. Selectable only after a datastore is chosen. | |
| Field (downstream) | Select | The downstream column. Selectable after the container is chosen. | |
| Field (upstream) | Select | The column on the locked container. |
Steps
Step 1: Open the container and go to its Lineage tab.
Step 2: Hover the right edge of the node you want to extend, then click Add downstream . You can also right-click the node and choose Add downstream .
Step 3: The Add downstream panel opens. The node you started from is shown locked, with a lock icon, in the upstream section.
Step 4: Choose the mode. Stay on the container tab to connect whole containers, or switch to Field to connect one column to another.
Step 5: In the downstream section, select the Datastore, then the Container. See the Field reference above for what each one holds in the mode you picked.
Step 6: In Field mode only, select the Field on the downstream side and the Field on the locked upstream side.
Step 7: Click Add. The button stays disabled until both ends are complete.
Step 8: The new node appears on the downstream side and the canvas re-centers on it.
Tip
Right-clicking a row in a node's expanded field list and choosing Add downstream opens the panel already in Field mode with that field selected, which skips two steps.
Note
When the two fields belong to different containers, Qualytics also creates the container-level connection between those containers if one does not exist yet, so the relationship is visible at both levels.
