why can't we just give the ownership? are we using the headers anywhere else?

the problem is every for loop iteration will be new scope ,if there was only one iteration it would have worked. @yhl25

why is the both key and value, UUID?

no need of that comment since we can clearly see it is Arc::clone

also move the headers inside the for loop, ideally each message will have different txn-id
