Hi I was thinking about making some workflows more event based.. but the worry would be that say the event is reacting to something from an external system/source.. but I only want the trigger to happen say once a day. Is this something you might use caching for? (e.g. if cache exists do nothing else carry on)

You could explore our events api, to create more event driven workflows. I can see an automation being kicked off based on that event, and then a deployment of your flow to be scheduled at a later time
