public interface Format
```
Base interface for connector formats.
Depending on the kind of external system, a connector might support different encodings for reading and writing rows. This interface is an intermediate representation before constructing actual runtime implementation.
Formats can be distinguished along two dimensions:
- Context in which the format is applied (DynamicTableSource or DynamicTableSink).
- Runtime implementation interface that is required (e.g. DeserializationSchema or some bulk interface).
A DynamicTableFactory can search for a format that it is accepted by the connector.
