File systems and object stores

Vertica supports access to several file systems and object stores in addition to the Linux file system.

Vertica supports access to several file systems and object stores in addition to the Linux file system. The reference pages in this section provide information on URI syntax, configuration parameters, and authentication.

Vertica accesses the file systems in this section in one of two ways:

  • If user-provided credentials are present, Vertica uses them to access the storage. Note that on HDFS, user credentials are always present because Vertica accesses HDFS using the Vertica user identity.

  • If user-provided credentials are not present, or if the UseServerIdentityOverUserIdentity configuration parameter is set, Vertica checks for a configured USER storage location. When access is managed through USER storage locations, Vertica uses the server credential to access the file system. For more information about USER storage locations, see CREATE LOCATION.

Not all file systems are supported in all contexts. See the documentation of specific features for the file systems those features support.
