Thomas Mueller commented on OAK-2490:
-------------------------------------

> It would be nice if we change the IndexPlan exposing this information to the 
> query engine

Yes, even thought I don't think this is a high priority. Sure, access rights 
checks can be avoided in this case, but I would expect this information is 
cached. There is a slight complication: the select list can contain other 
properties than the condition (select a from x where b = 1). So access rights 
checks for b are not enough in this case. If access rights are on the node 
level (all properties are readable, or none are readable) then this is not a 
problem.

> As discussed on OAK-2423 and OAK-2473 it's useful to have a 
> {{PermissionProvider}} down into {{QueryIndex}} implementations and/or 
> {{SelectorImpl}}, depending on wether the ACL checks have to be done on an 
> implementation base or generally.
