Delivery and retry

- [Narrator] How good would an event delivery mechanism,…such as Event Grid be, if it missed the notifications…of the messages you're trying to send.…Well, there are a lot of facilities built…into the Event Grid that basically,…your messages don't go missing,…and that's on Delivery and Retry.…So the Tenets, that Event Grid takes…on is that each message is tried…at least once for each subscription.…

And that events are sent to the registered endpoint…of each subscription immediately.…So, it's almost near real-time.…If the endpoint doesn't acknowledge…the receipt of an event, Event Grid will automatically…retry the delivery of that message.…See why we're thinking,…"why don't I just do storage queues?"…Well, then you'd have to built…this retry logic yourself, right?…So it does simplify a lot of things.…So, Retry Schedule and Exponential Backoff…is based on this schedule.…

So, first it tries it in 10 seconds,…in the event of a failure, if that fails…then 30 seconds, then one minute…and this progressively increases to one hour.…
