Deletes the specified volume.

When you delete a managed volume, the files stored in this volume are also deleted from your cloud tenant within 30 days.

If an external volume is dropped, the metadata about the volume is removed from the catalog, but the underlying files are not deleted.

To drop a volume you must be its owner, or the owner of the schema, catalog, or metastore the volume resides in.

Parameter

  • IF EXISTS

    If specified, no error is thrown when the volume does not exist.
