-------------------------------

             Summary: Using canal-json,debezium-json,maxwell-json serialization, The DELETE semantics should be interpreted.
                 Key: FLINK-19500
                 URL: https://issues.apache.org/jira/browse/FLINK-19500
             Project: Flink
          Issue Type: Bug
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
            Reporter: CaoZhen


When Using {{canal-json}},{{debezium-json}},{{maxwell-json}} serialization, the RowData of {{DELETE}} was not put {{old}} data into JSON message. I will open an issue to track it.

 

*For example，Maxwell-json:*

*the Rowdata：*

-U(106,hammer,16oz carpenter's hammer,1.0)

 

*active Maxwell-json serialization:*

{
    "data":{
        "id":106,
        "name":"hammer",
        "description":"16oz carpenter's hammer",
        "weight":1
    },
    "type":"delete"
}

 

*expected Maxwell-json serialization:* 

{
    "old":{
        "id":106,
        "name":"hammer",
        "description":"16oz carpenter's hammer",
        "weight":1
    },
    "data":null,
    "type":"delete"
}
