In what situation would a scheduled or polling approach be used?

A scheduled or polling approach is typically employed in scenarios where the underlying systems do not facilitate real-time event processing. Specifically, in the case of an HR system that lacks the capabilities to send updates or events immediately as changes occur, organizations must rely on alternative methods to gather and synchronize identity data. This may include setting up periodic polling to check for any changes rather than depending on instantaneous notifications.

Choosing this approach allows for the consistent retrieval of data updates on a predefined timeframe, ensuring that the identity system remains as current as possible, even in the absence of real-time support. Implementing a scheduled or polling strategy is therefore a practical solution to accommodate systems with limitations regarding event-driven architectures. Conversely, other scenarios, such as when real-time responses are essential or when comprehensive tracking is needed, would typically call for different strategies that can provide immediate feedback and detailed oversight.
