Alright, I'd like to think about this one specifically and solicit
feedback on the idea that we keep the existing shared role tables but
add on additional tables for per-database roles.
In the past, I feel like we've been focused on the idea of moving all
roles to be per-database instead of per-cluster, which certainly has a
lot of problems associated with it, but in the end, I think people would
be really happy with some shared roles and some per-DB roles.
What would the semantics of that look like though? Which is "preferred"
when you do a 'grant select' or 'grant role'? Or do we just disallow
overlaps between per-DB roles and global roles? If we don't allow
duplicates, I suspect a lot of the other questions suddenly become a lot
easier to deal with, but would that be too much of a restriction? How
would you handle migrating an existing global role to a per-database
role?
Thanks,
Stephen
