No isolation shared access mode
No isolation shared access mode is legacy, replaced by Standard and Dedicated access modes (legacy since December 2025).
Standard clusters No isolation shared access mode Shared / Single user access modes Standard and Dedicated access modes
The legacy compute access mode that shares a cluster across users without process isolation or Unity Catalog governance.
- It shared one cluster across users with no process isolation between them and no Unity Catalog governance - so, unsurprisingly, new accounts don't get it by default anymore.
- Admins can flip an account setting that disables credential sharing on these clusters.
- From September 30, 2026 every new workspace is provisioned without it, so the mode survives only in workspaces old enough to remember asking for it.
