Article Introduction：MySQL is a commonly used relational database management system. In practical applications, we often encounter scenarios that require data replication. Data replication can be divided into two forms: synchronous replication and asynchronous replication. Synchronous replication means that the data must be copied to the slave database immediately after the master database writes the data, while asynchronous replication means that the data can be delayed for a certain period of time after the master database writes the data before copying. This article will focus on how to implement asynchronous replication and delayed replication of data in MySQL. First, in order to implement asynchronous replication and delayed replication, I

Article Introduction：How to achieve instant replication of database in ReactQuery? Introduction: In the development of modern applications, real-time replication of databases is often involved. Instant replication means that when additions, deletions, and modifications occur in the database, the latest data can be automatically synchronized to the application. ReactQuery is a powerful tool for managing application data. It provides many useful functions to handle the fetching, updating and caching of data. This article will introduce how to use ReactQuery to implement data

Article Introduction：How to implement heterogeneous and homogeneous replication of data in MySQL? Introduction: In modern software development, database replication is a very important function. It can realize data backup, data read-write separation and high availability requirements. As one of the most popular relational databases, MySQL provides a variety of replication methods to meet the needs of different scenarios. This article will introduce how to implement heterogeneous and isomorphic replication of data in MySQL, and attach corresponding code examples. 1. Heterogeneous replication of MySQL data Heterogeneous replication refers to

Article Introduction：When we write concurrent programs, we often need to use locks to protect shared resources and prevent multiple goroutines from accessing and modifying these resources at the same time. The sync package is provided in the Golang standard library, which contains the implementation of multiple locks, such as mutex (Mutex), read-write lock (RWMutex), etc. In Golang, copying a lock refers to copying a copy of an existing lock, so that multiple goroutines can operate different lock instances at the same time without affecting each other. This can improve in some scenarios

Article Introduction：In CAD software, quickly viewing the boundary lines of entities is a very critical operating skill. This feature allows us to quickly copy, repeat or move the boundary lines of objects, thereby improving drawing efficiency and accuracy. By copying the boundary line of an entity, the user can create a copy that is exactly the same as the original boundary line while keeping the original shape unchanged. This can greatly save time and energy for users who often need to make similar or identical designs. Next, the editor of this website will bring you this article to guide you in detail on how to view the boundary lines of copied entities in CAD software. Hope it helps everyone. CAD copy entity boundary line method steps 1. Open the CAD2023 software and open the completed entity. As shown below: 2. Click More Settings, click Repeat
