What is the use of redis cache?

Redis cache is used to: reduce database load: cache frequently accessed data into memory. Accelerate page loading: cache static content and page elements to shorten page loading time. Session Management: Store user session data, offload databases and facilitate access. Real-time notification: Implement a publish/subscribe system for real-time updates. Queue processing: Implement message queue for asynchronous message transmission. Rate limiting: Limit access to specific resources to prevent abuse. Leaderboards and counters: Provide atomic increment operations, suitable for storing quickly updated values.

Uses of Redis cache

Redis is a popular open source, in-memory data structure storage that is widely used in a variety of applications to enhance performance and improve user experience.

Purpose of Redis cache:

• Reduce database load:Redis can be used as the cache layer of the database to store frequently accessed data in memory. This can significantly reduce the number of database accesses, thereby improving the overall performance of the application.
• Accelerate page loading: For web applications, Redis can be used to cache static content and page elements such as images, CSS, and HTML fragments. By storing these assets in memory, Redis can significantly improve page load times.
• Session Management: Redis can be used to store user session data, such as shopping carts, recently viewed items, and shopping cart information. This unloads the database and allows applications to easily access session data.
• Real-time notifications: Redis can be used to implement a publish/subscribe system, allowing applications to send real-time updates to subscribers. This is useful for applications such as chat applications, real-time analytics, and games that need to be updated to provide real-time information to users quickly.
• Queue processing: Redis can be used to implement message queues, allowing applications to send and receive messages asynchronously. This is useful for communication between different components in a distributed system.
• Rate Limiting: Redis can be used to limit access to application-specific resources to prevent abuse and service disruption. By storing requests in a queue, Redis ensures that they are processed at a controlled rate.
• Leaderboards and counters: Redis provides atomic increment operations, which makes it ideal for storing leaderboards, counters, and other values ​​that need to be updated quickly.
