Description
When querying a view, it would be useful to know which underlying base table partitions it depends on in order to know how fresh the result is (or to be able to wait until all of those partitions have been loaded consistently). The task is to come up with a way to perform this analysis automatically (possibly overconservatively), or alternately to let the view creator annotate the view definition with this dependency information, or some combination of the two.
Note that this would be useful for any complex query which directly accesses base tables (not just view definitions).
