good point, done
> Create unified interfaces to configure and instatiate TableSinks
> ----------------------------------------------------------------
>
> Key: FLINK-8866
> URL: https://issues.apache.org/jira/browse/FLINK-8866
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Shuyi Chen
> Priority: Major
> Labels: pull-request-available
>
> Similar to the efforts done in FLINK-8240. We need unified ways to configure
> and instantiate TableSinks. Among other applications, this is necessary in
> order to declare table sinks in an environment file of the SQL client. Such
> that the sink can be used for {{INSERT INTO}} statements.
> Below are a few major changes in mind.
> 1) Add TableSinkFactory/TableSinkFactoryService similar to
> TableSourceFactory/TableSourceFactoryService
> 2) Add a common property called "type" with values (source, sink and both)
> for both TableSource and TableSink.
> 3) in yaml file, replace "sources" with "tables", and use tableType to
> identify whether it's source or sink.
