Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Volumes are Unity Catalog objects representing 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. Volumes are siblings to tables, views, and other objects organized under a schema in Unity Catalog. For more details and limitations, see Create and work with volumes. 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. An external volume is a Unity Catalog-governed storage volume registered against a directory within an external location. A volume name is an identifier that can be qualified with a catalog and schema name in SQL commands.
