abstract class KafkaAvroKeyValueDeserializationSchemaFactory extends KafkaAvroDeserializationSchemaFactory

Abstract base implementation of KafkaAvroDeserializationSchemaFactory which uses Kafka's Deserializer in returned Flink's KeyedDeserializationSchema. It deserializes both key and value and wrap it in ConsumerRecord object (transforms raw event represented as ConsumerRecord from Array[Byte] domain to Key-Value-type domain).

    Prepare Flink's KafkaDeserializationSchema based on provided information.

    K

    Type that should be produced by key deserialization schema.

    V

    Type that should be produced by value deserialization schema. It is important parameter, because factory can use other deserialization strategy base on it or provide different TypeInformation

    kafkaConfig

    Configuration of integration with Kafka.

    keySchemaDataOpt

    Schema which will be used as a key reader schema.

    valueSchemaDataOpt

    Schema which will be used as a value reader schema. In case of None, writer schema will be used.
