Introduction

Data Push is a technique widely used in systems and applications that require real-time performance. Typically, a server automatically sends data to a client when the server has data or certain conditions are met. Data push can be implemented using a variety of technologies and protocols, including websockets, server push over HTTP/2, push notifications, and email notifications.

Applicable Scene

Scenarios where information needs to be delivered to users in real time, such as social media message notifications, stock price and weather updates, sports score reports, etc. When a user sends a message, the message must be delivered to the recipient immediately. Real-time data updates and alerts from IoT devices immediately notify the central server or management system. Applications that require real-time data updates on the browser (such as stock charts, online games, real-time collaboration tools).

Pros: Information can be sent from the server side before the client sends a request, allowing real-time data updates. Users do not need to manually update the latest information, providing a smooth experience. Network traffic is managed efficiently because the server only sends data when needed. This eliminates the need for client polling (periodically requesting data from the server), saving system resources.

Cons: Pushing data to many clients simultaneously can put a significant load on the server side. Push notifications assume that the client is connected to the network, and depending on network conditions, data may be delayed or not delivered. Pushing data externally can involve security risks and require additional security measures to prevent the risk of malicious data or unauthorized access.
