    @haohui We only cast ROWTIME / PROCTIME directly to LONG during runtime, the special types
are needed during pre-flight phase and validation. We could not come up with a better solution
that ensures that watermarks stay aligned with the rowtime.

> Currently {{DefinedRowtimeAttribute}} can define an appended rowtime field for a {{TableSource}}.
But it would be helpful if we can support to define an existing field as the rowtime field.
Just like registering a DataStream, the rowtime field can be appended but also can replace
an existing field.
