Timo Walther created FLINK-6870:
-----------------------------------
Summary: 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
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.
