Interface Format

  • All Known Subinterfaces:
    DecodingFormat<I>, EncodingFormat<I>, ProjectableDecodingFormat<I>
    @PublicEvolving
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.
