Vijay K updated TEIID-4717:
---------------------------
Description:
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 as user I should be able to configure the Cassandra translator to append *ALLOW FILTERING* to the generated query (CQL)

The Cassandra translator should support configuration (flag?) based support for appending *ALLOW FILTERING* to the generated query (CQL)
