I was wondering if you could provide a bit more detailed information about your use case?
what sort of datasource are you using?
what data is contained within your datasource? (just attribute values or whole payloads?)
Is it REST?
Is it JSON/XML?
What's the purpose of the datasink - are you just writing out the responses to the datasink and that's it?
you say Request X will be performed 5 times for every Request Y - how do you envision this working - Does RequestX have to execute before RequestY or the other way around or something different?
I couldn't really envision what the 2 columns of output you provided was supposed to represent
The more detailed info you provide the more likely someone's gonna be able to help you out,
if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
