Oh, yes.
> Add Kafka010JsonTableSink

> Key: FLINK-8014
> URL: https://issues.apache.org/jira/browse/FLINK-8014
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Fabian Hueske
> Assignee: Fabian Hueske
> Fix For: 1.4.0
>
>
> Offer a TableSource for JSON-encoded Kafka 0.10 topics but no TableSink.
> Since, the required base classes are already there, a
> {{Kafka010JsonTableSink}} can be easily added.
