tonychan updated FLINK-20880:
-----------------------------
Description:
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}
the schema is a,b,c running the code as bleow
Row row = new Row(RowKind.INSERT,3);
row.setField(0,1);
row.setField(1,2);
row.setField(2,3);
System.out.println(row);
a:1,2,3
b:1,null,3
c:1,null,3
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
