Sylvain Lebresne commented on CASSANDRA-5443:
---------------------------------------------
bq. K_EXISTS has not been added to unreserved keywords
Right, good catch, adding a patch to make that happen. I'm also not sure about
{{IF}} and {{NOT}}, it will weird to have them unreserved and I can't imagine
someone in his right mind using them as column name (I note that for the same
reasoning, {{NULL}} has been added as a reserved keyword recently).
