> Currently, debezium-json format only support deserialization, but not support serialization. This is not convenient for users to writing changelogs to an message queue. 
> The serialization for debezium-json can follow the json strcuture of debezium, but considering currently Flink can't combine UPDATE_BEFORE and UPDATE_AFTER into a single UPDATE message. We can encode UPDATE_BEFORE and UDPATE_AFTER as DELETE and INSERT debezium messages.
