Timo Walther updated FLINK-6870:
--------------------------------
Affects Version/s: 1.4.0
> Combined batch and stream TableSource can not produce same time attributes
> --------------------------------------------------------------------------
>
> Key: FLINK-6870
> URL: https://issues.apache.org/jira/browse/FLINK-6870
> Project: Flink
> Issue Type: Bug
> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Timo Walther
>
> If a class implements both {{BatchTableSource}} and {{StreamTableSource}}, it
> is not possible to declare a time attribute which is valid for both
> environments. For batch it should be a regular field, but not for streaming.
> The {{getReturnType}} method does not know the environment in which it is
> called.
