FOREACH Node: One Run Per Item, in Parallel

Point a FOREACH node at any list and it repeats one child run per item, in parallel, so one bad row never touches the rest.

What You Will Learn

  • Pointing a FOREACH node at any list, from a file upload, an API response or an earlier step
  • Defining the work for one item only, not the whole batch, and letting the node repeat it
  • Concurrency as a throttle: turn it up to finish faster, down when the system on the other end has a rate limit
  • Why each item gets its own independent child run and execution log, so one failure is isolated and debuggable
  • The cost warning before you press run: a thousand items means a thousand sets of model calls
  • Combining FOREACH with a USE CASE node for the standard batch pattern: build the single-item logic once, then loop it
