Hi Tao,
I think you just need an extra `isEmpty` VARIABLE and maintain it properly
(e.g., when restoring the job, check if the list state is empty or not).
Also, I remembered that the list state for rocksdb is not as performant as
the map state when the state is large. Sometimes you could use a m
any suggestion is highly appreciated
