Permission groups let you assign lakehouse permissions to a set of users instead of one by one. Use the Groups area in workspace settings to create and manage groups and to add or remove members from each group.
Groups are only available on Growth or Custom plans. On Starter, all members have Manager-level access to all data.
The All group
Every workspace has a built-in group called All that includes every user. New users are added to All automatically. You cannot edit, delete, or change membership of the All group. Owners, admins, and members with Manager permission on a resource can use the All group to grant or revoke access to all members at once.
How group and individual permissions combine
If a user belongs to a group that has Viewer access to a table but their individual permission on that table is Editor, they get Editor access. Nekt always applies the highest permission the user has from any group or direct assignment.
Only owners and admins can create and manage groups and manage which members belong to each group.
