you may not add the starrocks-thrift-sdk dependency

you can see StarRocksSerializerFactory#createSerializer

可以使用stream的方式，将数据包装成StarRocksSinkRowDataWithMeta后写入

The data format of the above figure is not a valid json. can you provide a example with the upstream data format for us?

PTAL @waittttting @banmoy
