Review comment:
       I'm not sure about this. 
   
   According to Cassandra docs, the `count` is a non-reserved keyword. And non 
reserved keywords doens't need single or double quotes. 
   
   > Reserved keywords cannot be used as identifier, they are truly reserved 
for the language (but one can enclose a reserved keyword by double-quotes to 
use it as an identifier). Non-reserved keywords however only have a specific 
meaning in certain context but can used as identifier otherwise.
