[I] [flink] Batch query on empty datalake-enabled table should return 0 rows instead of failing with UnsupportedOperationException [fluss]
binary-signal opened a new issue, #3207:
URL: https://github.com/apache/fluss/issues/3207
### Search before asking
- [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.
### Fluss version
main (development)
### Please describe the bug 🐞
When a Fluss table has `table.datalake.enabled = true` but is empty (no data written yet, so no lake snapshot has been tiered), running a batch query via Flink SQL fails with:
```text
java.lang.UnsupportedOperationException: Currently, Batch mode can only be supported if one lake snapshot exists for the table.
```
The expected behavior is to return an empty result set (0 rows). The Spark connector already handles this correctly by falling back gracefully.
### Solution
_No response_
