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

             Summary: Turn Json String into Row 
                 Key: FLINK-20880
                 URL: https://issues.apache.org/jira/browse/FLINK-20880

          Components: API / Core
    Affects Versions: 1.12.0
            Reporter: tonychan


schema has  three params ,a,b,c

message a：\{ "a": 1, "b": 1, "c": 2}   

message b：\{ "a": 1, "b": null, "c": 2}   

message c：\{ "a": 1,  "c": 2}   

 

turn message into row , message a is ok, but we cant distinguish message b and message c if we use null, when deal message c ,we must use like NaN row(2,NaN),  i think row need a easy way to show message b and message c  with row
