> The keyspace field in the sink isn't used anywhere
It is used in CassandraPojoSinkBuilder.createSink(), the keyspace is an
argument of `new CassandraPojoSink<>(...);`
```
@Override
public CassandraSink<IN> createSink() throws Exception {
return new CassandraSink<>(input.addSink(new
CassandraPojoSink<>(typeInfo.getTypeClass(), builder, mapperOptions,
keyspace)).name("Cassandra Sink"));
}
```
> and the configuration operations don't have any effect either
the keyspace is set in the configuration in the `"keyspace"` key.
```
if (keyspace != null && !keyspace.isEmpty()) {
configuration.setString("keyspace", keyspace);
}
```
which is then used to connect to cassandra with this keyspace:
`cluster.connect(configuration.getString("keyspace", null));`
Am I missing something ?
PS:
Instead of using the configuration object maybe we can just use `session`
that is just created to execute a `session.executeAsync("USE " + keyspace);`
like in Cluster.connectAsync(final String keyspace) ?
