When you do a lookup (resource or subject) call, I assume there is no way to get a sorted result back, right? I have been struggling to find an efficient way to do paged results that is sorted by a specific column too. Say you want to sort your documents by name or date and show the first 100. We can sort them in our main database, but now that permissions are stored in SpiceDB, we need to do a separate CheckPermission for these, which means some or all of the sorted results may be filtered out. That's why we started thinking about more genral graph databases. Do you have any recommendation for this specific problem?
