In a scenario where an account has a number of contacts. When a field on the account changes, need to propagate that value to all related contacts. I know it can be done with a visual flow and Apex trigger but not Process Builder. Could I use platform event to watch for that value change on the account and publish account Id and new value so related contacts can see it and update themselves by using a Process Builder?
In other words, can I utilize platform events to update children from a parent?
