Could anyone help me understand updating flows? Do I always need to re-register all my flows and flow of flows? I built a script that register all my flows and flow of flow. However everytime I make an update to my flows, it takes a long time as if it is running a whole cycle on the backend. Am I doing it right?

If you have a flow of flows you'll need to register the subflows if you update them. What kind of Storage are you using for your Flow?

the flows are pulling and push data to mysql.
