- [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.
### Description

### Willingness to contribute

Research direction
Start by examining the existing Union Read support through the Flink SQL/Table API and the Flink DataStream API entry points. Determine how DataStream users can read historical lake snapshot data alongside real-time Fluss data, then verify that this workflow is supported end to end.
