@PublicEvolving
public interface RuntimeConverter
extends Serializable
```
Base interface for converting data during runtime.
Instances of this interface are provided by the planner. They are used for converting between data structures or performing other mapping transformations.
Because runtime converters are Serializable, instances can be directly passed into a runtime implementation, stored in a member variable, and used when it comes to the execution.
