ProcessEventsInOrder Element (ADF)

Specifies whether Notification Services uses quantum sequencing or subquantum sequencing to process event and subscription rules.

Syntax

<ApplicationExecutionSettings>
    ...
    <ProcessEventsInOrder>

Element Characteristics

Characteristic Description

Data type

Boolean.

Default value

false (uses quantum sequencing).

Occurrence

Optional once per ApplicationExecutionSettings element.

Updates

Can be added, deleted, and modified when updating the application.

None.

Remarks

The ProcessEventsInOrder element configures quantum or subquantum sequencing. When using quantum sequencing, Notification Services fires the event and subscription rules once per quantum. When using subquantum sequencing, Notification Services fires the event and subscription rules when each event batch arrives, which might happen multiple times per quantum. Quantum sequencing is more efficient; subquantum sequencing ensures that events are processed in order as they arrive.

To use quantum sequencing, set ProcessEventsInOrder to false. To use sub-quantum sequencing, set ProcessEventsInOrder to true.

For more information, see Specifying the Event Processing Order.

Example

The following example shows how to configure the application to use quantum sequencing.

<ProcessEventsInOrder>false</ProcessEventsInOrder>
