And **your users** define in some way (for example in a web dashboard somewhere) the **URL** where your app should send those requests.

* Correctness at startup; with the sequencing above, items are only processed once all informers are synced. This means queries will not return stale data at startup.
* Deduping of identical events
* Automatic retrying of failed events (configurable)

The above logic is critical to handle correctly to ensure correctness of a controller.
