```
@Internal
public interface TransformationScanProvider
extends ScanTableSource.ScanRuntimeProvider, ParallelismProvider
```

- Method Detail
  - createTransformation
```
org.apache.flink.api.dag.Transformation<RowData> createTransformation(ProviderContext providerContext)
```
    Creates a Transformation instance.
    Note: If the CompiledPlan feature should be supported, this method MUST set a unique identifier for each transformation/operator in the data stream. This enables stateful Flink version upgrades for streaming jobs. The identifier is used to map state back from a savepoint to an actual operator in the topology. The framework can generate topology-wide unique identifiers with ProviderContext.generateUid(String).
