It's not about public/private :) It's about an order in which you should be
reading the code.
> Expose descriptor-based sink creation in table environments
> -----------------------------------------------------------
>
> Key: FLINK-9852
> URL: https://issues.apache.org/jira/browse/FLINK-9852
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Affects Versions: 1.6.0
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
> Labels: pull-request-available
>
> Currently, only a table source can be created using the unified table
> descriptors with {{tableEnv.from(...)}}. A similar approach should be
> supported for defining sinks or even both types at the same time.
> I suggest the following syntax:
> {code}
> tableEnv.connect(Kafka(...)).registerSource("name")
> tableEnv.connect(Kafka(...)).registerSink("name")
> tableEnv.connect(Kafka(...)).registerSourceAndSink("name")
> {code}
> A table could then access the registered source/sink.
