      Work Description: echauchot commented on issue #7340: [BEAM-6324] - 
Cassandra reader with query implemented
URL: https://github.com/apache/beam/pull/7340#issuecomment-460174749
 
 
   Regarding using the ITests to test cassandra, I think it would be better to 
do it in UTests. I understand why you chose ITests, because you wanted a proper 
cassandra instance to test against. This is why I pointed out using an embedded 
cassandra instance. I'm precisely refactoring CassandraIO to include such an 
embedded instance in UTests and also to remove CassandraService which was 
mainly there to enable injecting FakeCassandraService mock.
