Event Notification Priority
Event Notification Priority
This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.
When registering for synchronous event notifications, you can set a priority that specifies when the notification will occur relative to the other event registrations waiting on the same event. The registration priority can have any value within the ranges shown in the following table:
| Priority | Decimal value | Hexadecimal value |
|---|---|---|
| Highest (first to be notified) | 0 | 0 |
| Default | 65535 | 0x0000ffff |
| Lowest (last to be notified) | 2147483647 | 0x7fffffff |
Use the decimal value to register the priority.
Event registrations with the same priority can fire in any order. Priorities do not apply to asynchronous event registrations.
The following illustration shows synchronous sink execution by priority.

Recursive Sink Firing Order
Recursive event notifications in the parent folder occur before event notifications in the subfolders.
