Clean up retired external locations from one approval webhook
Turn an explicit cleanup decision into a controlled Databricks action with a useful result.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Delete External Location
Tool to delete an external location from Unity Catalog metastore. Use when you need to remove an external location that combines a cloud storage path with a storage credential. The caller must be the owner of the external location. Use force=true to delete even if there are dependent external tables or mounts.
Why this helps
Retired storage links linger because cleanup requires a precise, easy to forget admin step.
- Acts only on an explicit cleanup signal
- Reports dependency blockers clearly
- Keeps retired access surfaces from accumulating
Setup
Build it in a few focused steps.
- 1Connect Notis and Databricks in the portal once.
- 2Create an automation for approved external location cleanup.
- 3Tell Notis to delete only the external location named in the webhook and report dependencies or completion.
- 4Pick a webhook trigger.
- 5Choose a report destination and test with one approved cleanup event.
Questions about this workflow
Is deletion reversible?
Deleting the external location removes its Unity Catalog object, so confirm the webhook represents an approved cleanup.
What if dependent tables exist?
The action can fail or require force behavior; have Notis report the dependency response without guessing.
