Edge: Store & Forward vs. OPC-UA

@pturmel @Kevin.Herron
Phil, Kevin,
Apologies for revisiting this.

What about using MQTT to a client supplied MQTT broker to support data buffering?
We have the IIoT module and Edge IIoT description implies that store and forward should work here. Am I misunderstanding the this capability?

Sorry for not mentioning this initially, it slipped my mind here and I am still a relative newcomer to Ignition.

Thanks again.
