Flexible node type compatibility reference

This reference lists the instance type compatibility groups for flexible node types. When you configure a compute resource with flexible node types, Databricks can automatically fall back to compatible instance types if your preferred type is unavailable.

Compatible instance types within a group share the same vCPU count, memory (within 100-110%), local disk configuration, CPU architecture, and OS image support. For more information about flexible node types, see Improve compute launch reliability using flexible node types.

note

If an instance type shows 'None' for compatible types, it has no automatically generated fallback options. You can still specify a custom fallback list using the API if needed.
