Sylvain Lebresne commented on CASSANDRA-4269:
---------------------------------------------
Agreed. The problem here is really much of an implementation detail. We happen
to generate the CFDefinition object used by CQL3 in CFMetatData, and this even
if CQL3 is not used per se. So internally it's easier if the code support
non-utf8 columns, even though CQL3 won't allow to create them. Basically the
patch make sure we correctly convert column names to string when going in the
CQL3 side.
