Interface Converter

All Known Implementing Classes:

StringConverter

public interface Converter

The Converter interface provides support for translating between Kafka Connect's runtime data format and byte[]. Internally, this likely includes an intermediate step to the format used by the serialization layer (e.g. JsonNode, GenericRecord, Message).
