How much CU overhead is there when running Notebook with Workspace Identity.

We have lots of available capacity. We have different users and developers starting new sessions and running pipelines and complex scripts. We stop all that.

I can run a test Pipeline that calls a Notebook.

Once I use a connection object with Workspace Identity auth for the notebook....and set up the permissions, we get:

Notebook execution failed at Notebook service with http status code - '200', please check the Run logs on Notebook, additional details - 'Error name - Exception, Error value - Failed to create Livy session for executing notebook. Error: {"code":"BadRequest","subCode":0,"message":"Encountered internal error while calling TokenProvider to get obo token. The return code is BadRequest, and no error details was provided."

I do not believe this is a capacity issue. If it is, how much additional overhead would running the Notebook through a connection use? I can't image this would increase it. Does it? By how much?

Otherwise -- there is something broken in connections + Workspace Identity.

Is there a standard approach to get the security context (a guid that can be used to identify the account, user / account name) of the notebook execution?

I want to write that security context somewhere, so I want to know the standard way to retrieve it in consideration that the expected security context is different depending on how it’s run. I want to capture it though.
