Test

My simplified use case is blow:
I need to login to the System A, System B and System C and search for a specific Items and download the file. There will be 3 downloaded excel files in total with 1 file from each system.
File A and File B from System A and System B has columns 1,2,3 and 2,3,4. I need to do a union of column 2 from system A and 2 from System B, which acts as a item for System C.
So, basically, item1 is input for system A and System B and the output of union of columns will b the input for system C. Note: Item2 for system C can be much more then item 1.

I have to use the REFramework and possibly just 1 process. How do I design the architecture?

My idea:
Transaction Item - Item1, once the System A and System B is processed then add the items from union to a separate queue and start processing one by one. What I am worried about is the wait that system A and system B has to do because unless all items in second queue are not processed then System A and System B has to wait.

Can anybody give me an idea on how to approach this?strong text***[quote=“pravidhin, post:1, topic:724576, full:true”]
