@twalthr @sunjincheng121 `DefinedProctimeAttribute` and
`DefinedRowtimeAttribute` doesn't work in batch table source, currently. BTW, I
don't think batch table source needs `DefinedRowtimeAttribute`. Users can use
an existing column as the row time attribute without declare the column as a
rowtime, isn't that right ?
For the following example, the `ts` is a physical column in table `T`.
```sql
SELECT overAgg(b, a) FROM T GROUP BY TUMBLE(ts, INTERVAL '2' HOUR)`
```
