What is the main benefit of using the Streaming API?

The main benefit of using the Streaming API is its ability to provide real-time notifications for updates. This functionality enables applications to receive immediate updates about changes to Salesforce records without needing to poll the server constantly. By subscribing to particular events, clients can be notified instantly when changes occur, such as when a record is created, updated, or deleted. This is particularly advantageous for applications that require fresh data to provide a seamless user experience, such as dashboards and alert systems, enhancing responsiveness and reducing the latency associated with data retrieval.

This real-time capability distinguishes the Streaming API from other methods of data interaction, such as bulk data transfers or scheduled polling, which do not deliver immediate or on-demand updates. Therefore, organizations can leverage the Streaming API to build more interactive and responsive applications.
