fe -> elc : create bulk upload order
activate elc
elc -> elc : existing create order logic \n(check is eligible, \nget popcash balance,\nCOD KYC checking,\nisaccount suspended)
group looping orders
    elc -> elc : spawn goroutine
    elc -> db : get setting from db(insurance setting,\nshipment setting,etc)
    note right
        we can improve this, by moving the setting data to redis
    end note
    elc -> 3plagg : get weight rounding setting
    note right
        heads up !!! 
        at this point, we rely on 3pl-aggregator
        we must handle if we cannot hit 3pl-aggregator 
    end note
    3plagg --> elc
    elc -> elc : another logic process\n(get location by postal code or subdistrict name)
    elc -> elo : get rate (with redis cache)
    elo --> elc
    elc -> elc : another logic process (rts scoring, etc)

                    I think we can remove this block, because its useless
