> At certain times it is unavoidable to use few columns in the where clause which are not part of the index, in that case Cassandra driver throws error
> {color:red}Bad Request: Cannot execute this query as it might involve data filtering and thus may have unpredictable performance. If you want to execute this query despite the performance unpredictability, use ALLOW FILTERING{color}
> As a user I should be able to configure the Cassandra translator to append *ALLOW FILTERING* to the generated query (CQL)
