Mamta A. Satoor commented on DERBY-4191:
----------------------------------------
Rick, I really appreciate you taking the time on thinking about this jira. As a
start, I am thinking I will go ahead and work on
getMinimalSelectPermissionsList/getRequiredPermissionsListForCountStar()
approach. I think the actual implementation of that method will be required
even by the alternative approach you suggested. So, for now, I will work on
implementing the new method and have it used for count(*) case. Once I have
that working, we can see if we should add a new internal privilege type
MINIMAL_SELECT_PRIVILEGE and use that privilege type rather than internal
method calls to implement the final solution. Once I have some kind of code
ready, I will post it to this jira so we are more clear on what I am proposing
to do. Thanks.
