---------------------------------------
Github user StephanEwen commented on the issue:
https://github.com/apache/flink/pull/5538
I see the need for the feature, but I am skeptical concerning the
implementation.
This PR reflectively modifies the contents of a String. This is prone to
cause problems, for multiple reasons. Strings cache hash codes, and strings
themselves are interned and shared.
Is there no other way to pass a default namespace to the mapping?
> Add a default keyspace to CassandraSink
> ---------------------------------------
>
> Key: FLINK-8655
> URL: https://issues.apache.org/jira/browse/FLINK-8655
> Project: Flink
> Issue Type: Improvement
> Components: Cassandra Connector
> Affects Versions: 1.4.0
> Reporter: Christopher Hughes
> Priority: Minor
> Labels: features
> Fix For: 1.6.0
>
>
> 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.
