Parallel processing in case lifecycle
I have one stage containing three processes. The first one should finish before going to the other ones.
The second and third should be parallel processes. So it becomes something like:
Stage X
Process 1
Process 2 || Process 3
I can add Process 3 as a parallel process, but will this do the trick? Or will Process 1 and 3 start at the same time then?

@Joris Claus When you have 3 parallel processes, all the 3 processes runs parallel. What you can do is, keep a work queue in the beginning of 2nd and 3rd process. In the end of 1st process you can keep an utility shape calling an activity to resume flow(2nd and 3rd). So till you resume, the assignments will be waiting in the work queue.

@Anoop KrishnaWould it also make sense to change the stage configuration here to have its processes run synchronous instead? The first process would then by default be synchronous. The second and third processes can be made asynchronous by, for example, using subprocesses that are spun-off (if main processing may continue) or by using a split-join that continues when tasks within the second and third process have been completed.
I suppose the question is mostly, does it make sense to manipulate this particular parallel processing option in favor of other options? In theory it should work and it's not much work either, but I see a case for multiple solutions.

@BasRulesMatter! yeah, we have multiple solutions for this question. But In the example you mentioned 2nd and 3rd process doesn't wait till 1st process right or am I missing something?

@Anoop Krishna The 2nd and 3rd would wait if we make the 1st synchronous and not use the stage parallel processing option:
1st -> synchronous
2nd -> start after completion of 1st
3rd -> start after completion of 1st
