> Instead of requiring a user to set up a scanner with any column and scan the table to gather all row keys while ignoring the column value we should have a fast and lightweight scanner that for example takes a "null" for the column list and then simply returns only the matching keys of all non-empty or deleted rows. Filters should still be applicable.
