> Currently Cassandra does not have an existence check API. Because of this, data needs
to be read and thats how you know whether data is present or not. 
> This is not optimal because one replica needs to provide data. Instead a new API could
be exposed where each replica only sends out hash of the data. Repairs and other stuff can
happen like a normal read call.
