> I want to use flink sql to write kafka messages directly to hdfs. The
> serialization and deserialization of messages are not involved in the middle.
> The bytes of the message directly convert the first field of Row. However,
> the current RowSerializationSchema does not support the conversion of bytes
> to VARBINARY. Can we add some special RowSerializationSchema and
> RowDerializationSchema ?
