-------------------------------------
Hi [~xuyangzhong] , [~xu_shuai_] !
1) The RowKind can't be fixed in current architecture, because +I and +U are
separated in different batches in this example. And this would be are bit
tricky to fix it.
2) But the records order is really incorrect in this example and it can be
easily fixed - https://github.com/rovboyko/flink/tree/fix/FLINK-34380
