Does it Aggregation reply node preserve the order of the response with respect to original request?
For example if the fan out flow sends out 3 requests 1,2,3 then lets say response from process 2 always comes early compare to request 1 & 3 then can we do some configuration that fan in flow (having the aggregation reply node) always creates folder structure with response from 1,2,3 in that order only.
In my test, aggregation node combine responses in the order it receives them. I wanted to confirm if this is the default behavior or i have missed something. |

If you want responses to come in some particular order, you need to send them in serial, rather than in parallel. The aggregation nodes are designed to let you run a set of requests in parallel, rather than one at a time.

It's not the default behavior - it's the only behavior. Suppose response 2 didn't return; the folder would still be 1,3 and therefore out of order to the original request.
