Standard and Dedicated access modes

Standard and Dedicated access modes is the current Databricks name, previously Shared / Single user access modes (since March 2025).

No isolation shared access mode → Shared / Single user access modes → Standard and Dedicated access modes

Compute access modes that determine Unity Catalog support, language availability, and whether a cluster is shared.

• 'Shared' became 'Standard' and 'Single user' became 'Dedicated' in 2025 - then 'Dedicated' clusters were promptly allowed to be shared with a group, making the new name ironic on arrival. 🔗
• A new 'Auto' mode now just picks the recommended access mode for you. 🔗

⚠ Limitations: On Standard access mode, Databricks Runtime for ML, GPU compute, R, RDD APIs, spark-submit tasks, Hive UDFs, the Scala SparkContext, and streaming socket sources aren't supported; compute runs as a low-privilege user with restricted filesystem access and can't reach the instance metadata service or other services in the Databricks VPC. 🔗
