Timo Walther updated FLINK-8436:
--------------------------------
    Description: 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.  (was: 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.)
