----------------------------------------
Hi, [~jark], could you please assign this to me? I would like to encode the mentioned above as debezium messages.

> Key: FLINK-18823
> URL: https://issues.apache.org/jira/browse/FLINK-18823
> Project: Flink
> Issue Type: Sub-task
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table SQL / Ecosystem
> Reporter: Jark Wu
> Priority: Major
>
> 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.
