What is a common use of platform events in Salesforce?

Platform events in Salesforce are designed to facilitate real-time integration by enabling the propagation of changes and information between different systems or applications in a timely manner. They are based on a publish-subscribe model, which allows various components of the Salesforce ecosystem, as well as external systems, to communicate efficiently with one another.

When an event is published, any subscribers—including Salesforce applications or external systems—can respond in real time to this event, thus making it suitable for scenarios where immediate updates or notifications are crucial, such as in inventory management, order processing, and other interactive business processes. This capability enhances the responsiveness of systems and improves the overall user experience by providing timely updates, which is essential for applications that rely on quick data changes.

In contrast, sending emails is a separate functionality that does not leverage platform events; it utilizes built-in email services and automation tools within Salesforce. Storing data permanently is not a use case for platform events either, as they are intended for transient messages that signify events rather than holding stateful data. Creating new Salesforce users is also unrelated to platform events since user management falls under administrative functionalities rather than event-driven architectures. Hence, the primary and most suitable use of platform events focuses on enabling real-time integration.
