+<p id="kafka-scenarios__p5623971411818">For example, Kafka can be used to send a notification email and SMS message after a user has registered with a website, providing fast responses throughout the registration process.</p>

Traffic bursts from upstream systems with high processing capabilities may have a large impact on downstream systems with lower processing capabilities. For example, online sales promotions involve a huge amount of traffic flooding into e-commerce systems. Kafka provides a three-day buffer by default for hundreds of millions of messages, such as orders and other information. In this way, message consumption systems can process the messages during off-peak periods.</p>
