Can you clarify the relationship between ObservationTime messages and ReadTime messages?
I’m thinking that if you can receive 100 OT messages into the same orchestration, then an RT message that kicks off your third message, why do you need to worry about the time that they come in? Or is it that the RT message can only be associated with those OT messages received < 3 seconds ago? If you don’t need to worry about the time, just create your correlation on MessageType.
In terms of practically writing this orchestration, You will need a parallel orchestration to accept OT messages on one side and RT messages on the other. On the RT side of the parallel shape, you will need to create a sequential convoy to accept the OT messages in a loop. However, this is a bit theoretical and I’m assuming that you can do this – you will need to try it out.
