> If you’re using the iterator with reuseVectorSchemaRoot set to false, the
> first n-1 VSRs returned by a call to next() have their resources managed by
> the client code, but the last one gets closed when the iterator is closed.
> This is inconsistent and contradicts the javadoc for next:
> * If \{@link JdbcToArrowConfig#isReuseVectorSchemaRoot()} is false,
> * the client is responsible for freeing its resources.
> The iterator calls close on its CompositeJDBCConsumer instance, which in turn
> closes the vectors held by each consumer.
>
> {{@Override}}
> {{public void close() {}}
> {{ if (config.isReuseVectorSchemaRoot()) {}}
> {{ nextBatch.close();}}
> }
> {{ compositeConsumer.close();}}
> {{}}}
