-------------------------------------

E.g. 
{code}
   create table test (m text, n text, o text, p text, primary key (m, n, o));
   create index p on test (p)

   grunt> cassandra_data = LOAD 'cql://test/test?use_secondary=true' USING CqlStorage()
;
   grunt> filter_data = FILTER cassandra_data by p  == 'p1';                          
  
   grunt> dump filter_data;           
{code}
