App Workspace confusing while notebook is running

[gweis]

While a notebook is running, all the files are synced to the notebook storage.
Browse and up/download in the workspace UI connect directly to object store. So changes done in notebook server (while notebook is running) don't show up in object store.

Also any changes done to workspace will be overwritten by sync back when notebook shuts down.

Need a solution for that.

Possible quick fix:

Lock workspace browser while sync is in progress.

Connect workspace browser directly to notebook server (or webdav endpoint) while notebook is running.

Also let user only spawn notebook when there is no upload to object store in progress (may need to consider eventual consistency here as well)

Lock workspace browser while sync is in progress.

We could extend that to "lock workspace browser when notebook server up" and put a message saying words to the effect of "contents you see here is read-only and not up to date with notebook server X which is currently active."

Connect workspace browser directly to notebook server (or webdav endpoint) while notebook is running.

If we do end up with multiple notebook server instances this would be a problem (not sure how likely we're going to do multi-instance though.)

Is there the possibility of just one-way syncing from Jupyter to the object store at certain intervals even while the notebook server is running? We can still put a "data here may be up to X minutes old/stale and this is read-only while the notebook server is running" message but at least people don't have to shut down the notebook server to get stuff out.
