> Allow implementing both RetractTableSink and BatchTableSink in one class
> ------------------------------------------------------------------------

> Key: FLINK-8436
> URL: https://issues.apache.org/jira/browse/FLINK-8436
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Legacy Planner
> Reporter: Timo Walther
> Priority: Major
> Labels: auto-unassigned
>
> When implementing a table sink that should have the functionality of both a
> {{RetractStreamTableSink}} and {{BatchTableSink}} the current interface
> design has clashes in {{TableSink.getOutputType}}. We should clean/rework the
> interfaces there. Additionally, the return type should be
> {{TypeInformation<Tuple2<Boolean, Row>>}} instead of
> {{TupleTypeInfo<Tuple2<Boolean, Row>>}} to be more generic.
