6.46Another interview scenario

We need Account data from Salesforce, open invoices from billing, and subscription state from another API before returning a customer summary.

Answer:

“Those are independent reads, so Scatter-Gather is a good fit. I'd call the three systems in parallel, then use DataWeave to aggregate the route results into our API contract. I'd also define whether failure of any route is fatal or whether the API supports degraded/partial responses.”

Excellent.
