Which three approaches should be considered when selecting the correct API for notifying users of data updates in real time?

Choosing the Streaming API to support push notifications to users on mobile devices using Salesforce1 is an optimal approach when real-time user notifications are required. This API effectively facilitates real-time communication by enabling Salesforce to push updates to clients, reducing latency compared to polling methods. It operates in a way that is efficient and responsive, ensuring that users receive immediate updates without manual intervention.

Streaming APIs are designed to handle high volumes of data and can quickly convey changes occurring within Salesforce. When implemented in mobile applications like Salesforce1, this leads to an enhanced user experience, as the app can dynamically refresh its content based on the data changes without requiring users to refresh or check manually. This proactive capability is essential for maintaining a seamless and engaging mobile interface.

In contrast, continuous polling through a REST API, while functional, is less efficient as it consistently queries the Salesforce server for updates, which can result in a greater load on the server and potentially lead to latency in updates being displayed to users. The generic streaming API might offer flexibility in integrating with other systems, but it does not specifically tailor to mobile user requirements and may lack the dedicated optimization that the Salesforce Streaming API provides. The option utilizing ActionPoller involves more overhead with Apex callouts, introducing complexity and delay, which is less
