Hi @ibmfur
Here's what I recently received from Adobe Support
The Event Subscriptions Manager has confirmed the following:
We guarantee an event will be triggered within a respectable timeframe i.e. we don't consider a long delay until our average delivery time is above 5 minutes.
Our p90 delivery time hovers around 5-10 seconds usually, but there are times when we have very high traffic among many customers,which can cause delays up to that 5 minute mark.
We are working on ways to reduce that time, but right now, customers should expect to occasionally have delays.
In other words - there can be significant delays and there's no fix for it.
To be fair, I see most scenarios received their events within 1-5 second. Fusion execution is quick as well.
The point to make with your client is that Fusion is not a way to create an interactive Workfront experience. Fusion is an integration platform, SaaS, and as part of its architecture, message/actions get queued. If there's congestion, you will see delays.
I explain Fusion as "macros that automate what a human could/would do" - and that means some changes won't always happen as fast as we'd like, from a UX perspective.
So net-net: I am not worried about Fusion "uptime" - it's been pretty solid in my experience. Educate your client about Fusion, and that "immediate action" is a misplaced expectation.
