>                 Key: FLINK-8655
>                 URL: https://issues.apache.org/jira/browse/FLINK-8655
>             Project: Flink
>          Issue Type: Improvement
>    Affects Versions: 1.4.0
>            Reporter: Christopher Hughes
>            Priority: Minor
>              Labels: features
>             Fix For: 1.5.0
> Currently, to use the CassandraPojoSink, it is necessary for a user to 
> provide keyspace information on the desired POJOs using datastax annotations. 
>  This allows various POJOs to be written to multiple keyspaces while sinking 
> messages, but prevent runtime flexibility.
> For many developers, non-production environments may all share a single 
> Cassandra instance differentiated by keyspace names.  I propose adding a 
> `defaultKeyspace(String keyspace)` to the ClusterBuilder.  POJOs lacking a 
> definitive keyspace would attempt to be loaded to the provided default.
