_vindex is a system space that represents a virtual view. The structure of its tuples is identical to that of _index, but permissions for certain tuples are limited in accordance with user privileges. _vindex contains only those tuples that are accessible to the current user. See Access control for details about user privileges.

If the user has the full set of privileges (like ‘admin’), the contents of _vindex match the contents of _index. If the user has limited access, _vindex contains only tuples accessible to this user.


  • _vindex is a system view, so it allows only read requests.
  • While the _index space requires proper access privileges, any user can always read from _vindex.
