Hi everyone,

We work with sensitive data in Databricks, so it's crucial from both security and regulatory perspectives to purge all data saved in notebook revisions.

Currently, there are two manual methods:

1. Delete all history from each notebook individually.

2. Permanently purge all revision history via Settings -> Advanced for all notebooks.

Is there any way to automate this process?

I noticed that the API endpoints used for this are not documented:

• {workspace_url}/dataretention/purgehistorybefore/{purge_before_ms}

• {workspace_url}/notebook/{notebook_id}/history/clearall

I've tested calling these endpoints; although I receive an HTTP 200 response, the history does not actually get purged.

Has anyone managed to automate notebook revision purging successfully?
Any guidance would be greatly appreciated!
