Course Introduction：Redis is needed to speed up the combination of PHP and MySQL, because Redis can significantly increase data access speed and reduce database query burden. Specific methods include: 1. Cache MySQL query results into Redis to reduce the number of direct queries; 2. Use publish-subscribe mode or transaction to ensure cache consistency; 3. Prevent cache penetration through Bloom filters; 4. Set different expiration times or use distributed locks to avoid cache avalanches; 5. Implement hierarchical cache, data warm-up and dynamic adjustment strategies to further optimize performance.

Course Introduction：Redis accelerates existing applications: cache queries to reduce server load Core points: Redis effectively accelerates existing applications by caching query results, thereby reducing server stress. It stores query results for a specified time (for example, 24 hours), and then reuses these results, significantly improving application speed. The installation of Redis can be done through the operating system package manager or manually. The installation process includes avoiding common warnings and ensuring that Redis starts automatically after the server restarts. The Predis library works with Redis to provide a memory cache layer for applications. This process involves checking whether the results of the current query exist in the cache, if not, get the result and transfer it

Course Introduction：In Laravel, Redis and Memcached can be used to optimize caching policies. 1) To configure Redis or Memcached, you need to set connection parameters in the .env file. 2) Redis supports a variety of data structures and persistence, suitable for complex scenarios and scenarios with high risk of data loss; Memcached is suitable for quick access to simple data. 3) Use Cachefacade to perform unified cache operations, and the underlying layer will automatically select the configured cache backend.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
