Subject [jira] [Commented] (FLINK-8655) Add a default keyspace to CassandraSink

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

Github user zentol commented on the issue:

    That the example doesn't work isn't related to this PR so I'll merge it as is.
    But I'll take a look what the problem is, and either fix it or open a JIRA.

> 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.
