RegistryAvroDeserializationSchema

public RegistryAvroDeserializationSchema(Class<T> recordClazz,
                                         @Nullable
                                         org.apache.avro.Schema reader,
                                         SchemaCoder.SchemaCoderProvider schemaCoderProvider)

Creates Avro deserialization schema that reads schema from input stream using provided SchemaCoder.

参数:

recordClazz - class to which deserialize. Should be either SpecificRecord or GenericRecord.

reader - reader's Avro schema. Should be provided if recordClazz is GenericRecord

schemaCoderProvider - schema provider that allows instantiation of SchemaCoder that will be used for schema reading
