| Regarding the sequencing, it is a business requirement . An example in the financial field, one of messages could be an order to "buy", a following message could be a "sell". A sell can not come before the buy. The time difference between the messages could be less than a minute, or it could be a day, but the sequence should be respected. |

You simply can not guarantee message order, you can only hope for it...
so better take care of inconsistencies in your application, i.e. hold the sell order until the buy has completed...
