For details on uploading and managing files in volumes, see Upload files to a Unity Catalog volume and File management operations for Unity Catalog volumes. Volumes are Unity Catalog objects that represent a logical volume of storage in a cloud object storage location. Volumes provide capabilities for accessing, storing, governing, and organizing files. While tables provide governance over tabular datasets, volumes add governance over non-tabular datasets. You can use volumes to store and access files in any format, including structured, semi-structured, and unstructured data. You cannot use volumes as a location for tables. Volumes are intended for path-based data access only. Use tables for storing tabular data with Unity Catalog. A managed volume is a Unity Catalog-governed storage volume created within the default storage location of the containing schema. Managed volumes allow the creation of governed storage for working with files without the overhead of external locations and storage credentials. You do not need to specify a location when creating a managed volume, and all file access for data in managed volumes is through paths managed by Unity Catalog.
