Make Router vs Iterator: parallel branches or a queue, and people confuse them constantly.

Make Router vs Iterator: parallel branches or a queue, and people confuse them constantly.

HEARD: the most common Make mistake we see is using a Router to 'loop' over an array. A Router splits one bundle into parallel paths. An Iterator unpacks an array into many bundles processed one after another. Wrong choice and you either drop items or hammer an API.

The clean rule:
— Different actions on the same record: Router.
— Same action on many records: Iterator, then an Aggregator to stitch results back.

Get this pairing right and your operations count drops hard. Watch this.
