ReferenceApplies to: Unified engine deployments
storage_root
Set one root for all Unified durable state. A config file must include this field.
A local directory or file:// URL is also supported. A bare local launch uses the application’s data directory. Metadata, table files, results, telemetry history, and the secret key use fixed paths below the root.
Separate backend and location fields are rejected. Changing the root does not move data. See storage layout and access.Last modified on November 4, 2026
