Hi lei,

What's kind of doing different things?
Is there any related use case for this issue? Did you get any issue from your scenario?
Best regards

I checked it does affect. For example every time iterate, golbal value add 1, and print it .This parallel result won't be like 1,2,3,4,5... I change my job logical, and solved this
