Keep external data context aligned with Canvas discussions
Capture a useful discussion decision in the Databricks metadata record connected to that data source.
Trigger
New Canvas Discussion Message
Polls Canvas discussion topics for new messages.
Action
Update External Metadata
Tool to update an external metadata object in Unity Catalog. Use when you need to modify metadata about external systems registered within Unity Catalog. The user must have metastore admin status, own the object, or possess the MODIFY privilege. Note that changing ownership requires the MANAGE privilege, and callers cannot update both the owner and other metadata in a single request.
Why this helps
Useful data decisions can stay buried in course discussions while the related external metadata remains stale.
- Keep relevant data context close to its catalog record.
- Avoid manually revisiting discussion threads.
- Have the instruction define which messages warrant an update.
Setup
Build it in a few focused steps.
- 1Connect Canvas and Databricks once in the Notis portal.
- 2Create an automation instructing Notis which discussion decisions should update which external metadata record.
- 3Choose New Canvas Discussion Message for the intended course discussions.
- 4Select where run reports should be delivered.
- 5Test with one real message and confirm the correct metadata object is updated.

What does the Databricks action change?
