RegistryAvroSerializationSchema

public RegistryAvroSerializationSchema(Class<T> recordClazz,
                                       org.apache.avro.Schema schema,
                                       SchemaCoder.SchemaCoderProvider schemaCoderProvider)

Creates a Avro serialization schema.

参数:

recordClazz - class to serialize. Should be either SpecificRecord or GenericRecord.

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

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