flink解析复杂protobuf，注册成table遇到问题

目标：kafka protobuf--》row--》table--》sql--》hdfs。问题：protobuf是嵌套结构，转成row时，制定type出现问题。第一步：自定义反序列化方式，将protobuf转成row第二步：for循环放入row第三步：指定字段name和type时不生效因为protobuf有嵌套，所以此处用Types.POJO。这个用法是否问题？

请教下，Flink里面把流注册为表: tableEnv.registerDataStream("mytable", mystream ....) 这里的流 mystream 貌似必须是append only流，不能是retraction流。这是为什么？如果是retraction流，报错Table is not an append-only table. Use the toRetractStream() in order to handle add and retract messages.
