Github user bowenli86 commented on the issue:

    Hi @yunfan123  Thanks for the feedback, and I agree with you.
    Well, here's the problem: Flink seems to be using the StringAppendTestOperator as merge
operator from RocksDB, which added a ',' between values. But I didn't find how a java class
for StringAppendTestOperator. 
    Shall we mimic StringAppendTestOperator and concatenate the values with ',' ourselves?
Do you have any more suggestions?
