[jira] [Created] (FLINK-18823) Support serialization for debezium-json format

Jark Wu created FLINK-18823:
-------------------------------

             Summary: Support serialization for debezium-json format
                 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


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.
