- Redis implements common caching strategies
- With the continuous development of Internet technology, data processing and transmission have become more and more important, and caching technology, as an important means of optimizing performance, has attracted more and more attention. As a high-performance cache database, Redis is often used to improve the performance and efficiency of web applications. This article will introduce how Redis implements common caching strategies. Cache invalidation strategy Cache invalidation means that the data stored in the cache becomes invalid due to time or other reasons. In order to ensure the real-time nature of the data, we must set up a cache invalidation policy. Redi

- Comparison and application scenarios of Redis and MySQL
- With the development of Internet technology, the amount of data and visits have increased rapidly, and the storage and query pressure on the database has become increasingly huge. As a traditional relational database, MySQL can achieve efficient data reading and writing and transaction processing. However, when faced with massive data and high concurrent reading and writing, there are performance bottlenecks and scalability issues. As an in-memory key-value storage database, Redis has the advantages of high speed, high concurrency, and scalability, and has gradually become a highly respected cache and distributed storage solution. This article will start from Redis and MySQL

- Redis cache penetration processing: causes and solutions
- Redis cache penetration refers to a situation where a malicious user or attacker bypasses the cache and directly accesses the database by sending a large number of invalid queries. When a request queries for data that does not exist in the cache, Redis will send the request to the database for query. If the query conditions are illegal, the database will return empty query results. However, due to the presence of a large number of invalid query pressures, the database Too many resources will be used to process these queries, causing system performance bottlenecks. There are many reasons for Redis cache penetration, such as checking
