I have a question, If there are too many concurrent request how it will handle the last inserted queue and process it? I think there is high chances of order juggling for example if A -> alice ,B->bob, C->charlie, D->deco, E->erik,F->faun 6 order request are in same micro seconds then there is a chance that request from deco receiving response from bob and all may have others response! Did you get my point?
