With an implementation of lineage interfaces, Kafka source and sink provide
TypeDatasetFacetwhich contains type information of data processed. This was working with extracting type information fromSerializationSchema:However, this ain't working for
ConfluentRegistryAvroSerializationSchemadue to type erasure.As a workaround,
TypeDatasetFacetcan be extended to containSerializationSchemawhen direct extraction ofTypeInformationis not possible. This allows handling this case on the lineage listener side, while keeping flink-connector-kafka unaware of Avro type extraction logic.
