Course Introduction：This course develops the Jane Eyre reading project using a completely separated front-end and back-end approach. The front-end uses the uniapp framework, a set of popular code multi-end applications, and the back-end uses thinkphp6.0 to provide interface data and deploy it online (pagoda). To study this course, you need to have certain uniapp basics, such as conditional compilation, WeChat login, network requests, local caching, component development, etc. In addition, you also need to have certain thinkphp foundation, such as routing registration, cross-domain processing, file upload configuration, database query, etc...

Course Introduction：Use Redis to implement read-write separation code by connecting a write server and multiple read servers: 1. Write operations are performed using the write server client; 2. Read operations are performed using the read server client; 3. Ensure data consistency needs to be performed regularly Synchronize data between write server and read server.

Course Introduction：The read-write lock can allow multiple multi-threads to access at the same time, but when the write thread accesses, all read threads and other write threads will be blocked. Read-write locks actually maintain a pair of locks, one read lock and one write lock. By separating read locks and write locks, its concurrency is greatly improved compared to exclusive locks (exclusive locks).

Course Introduction：Golang is a very popular modern programming language that supports high-concurrency and high-performance application development. In Golang, read-write lock is a common synchronization mechanism that allows multiple coroutines to read shared variables at the same time, but only allows one coroutine to write shared variables. In this article, we will introduce how to implement read-write lock using Golang. The basic principle of read-write lock Read-write lock is a synchronization mechanism that allows multiple coroutines to read shared variables at the same time, but only allows one coroutine to write shared variables. Read-write locks can effectively improve concurrency performance because it allows

Course Introduction：MySQL read-write separation is a database architecture that divides the database into a master database and a slave database. The master database is responsible for write operations, and the slave database is responsible for read operations, so as to reduce the load of the master database and improve concurrent reading capabilities. Implementing MySQL read-write separation requires: setting up a master-slave replication environment, modifying application configuration, and using agents or middleware. The advantages of reading and writing separation include: reducing the main library load, improving concurrent reading capabilities, and providing data backup. It should be noted that read and write separation is suitable for scenarios where there are far more read operations than write operations.
