---------------------------------
@ [~paul8263]
i tested with Flink 1.13.3 ,
in batch mode ,output is :
(ALICE,1)
(ALICE,2)
(BOB,1)
(LILY,1)
(LILY,2)
(LILY,3)
in streaming mode ,output is :
(ALICE,1)
(ALICE,2)
(BOB,1)
(LILY,1)
(LILY,2)
(LILY,3)
flink 1.13.3, both outouts result are same. i think the streaming outouts is
correct, but the batch outouts is wrong.
flink 1.14.2, both outouts the are different. only the streaming outputs is
correct , the batch outouts is wrong yet.
> wrong result if table transfrom to DataStream then keyby sum in Batch Mode
