Fabian Hueske commented on FLINK-10999:
---------------------------------------
Hi,
Processing-time and event-time are supported in the same table.
You have a type mismatch some where in your code. It's not easy to tell where
exactly, because your example is quite complex.
I'd assume you try call .rowtime on a Timestamp attribute (should be a Long
attribute).
> Adding time multiple times causes Runtime : java.sql.Timestamp cannot be cast
