> Perhaps this should be part of replacing super columns with composites, but we essentially need something analogous to sub-column validators for when composites are used in a way that's similar to super columns (multiple fields for each "super column" in a row).  As an example use case, suppose you have a wide row holding users where the comparator is (<user_id>, <field>), and <field> might be either "name" or "age"; ideally, you can validate "name" as UT8Type and "age" as IntegerType.
> Allowing wildcards to be used for components in the column name portion of the ColumnDef might be a reasonable approach.
