> In {{AbstractCompositeType.validate()}}, there isn't any kind of check to verify that the data has the same number of components as the comparator (or validator).  This means that if you say the comparator is {{CompositeType(UTF8Type, UTF8Type)}}, you can use column names that only have the first component (ie, the last thing in the bytestring is the eof for the first component).
> This behavior isn't explicitly stated anywhere.  Personally, I wouldn't expect this to validate, but I could see an argument for why it should.  Either way, we need to either check the number of components or explicitly state that this is expected behavior.
