@PublicEvolving
public interface DecodingFormatFactory<I>
extends FormatFactory

Base interface for configuring a DecodingFormat for ScanTableSource and LookupTableSource.

Depending on the kind of external system, a connector might support different encodings for reading and writing rows. This interface helps in making such formats pluggable.

The created Format instance is an intermediate representation that can be used to construct runtime implementation in a later step.
