Database distributed management skills in MySQL

In large-scale application systems, it is often necessary to use database distributed management technology to improve system performance and scalability. MySQL is a popular open source relational database management system that also supports distributed management. In this article, we will introduce some database distributed management techniques in MySQL.

1. Sharding technology

MySQL sharding technology is a database distributed management technology. It distributes data to different servers by dividing a large database into multiple small databases. , effectively improving the operating efficiency of the database. The partition table of MySQL Server 8.0 or above supports horizontal partitioning. Table data can be dispersed into different partitions by specifying partition keys. The amount of data in each partition is relatively balanced, which improves the load balancing effect.

2. Read-write separation technology

MySQL read-write separation technology is a commonly used database distributed management technology. It places read and write operations on different servers. Greatly improve the efficiency of data reading and writing, and reduce the load on the database server. MySQL achieves read-write separation by building a master-slave cluster. The master server is responsible for write operations, and the slave server is responsible for read operations. Applications can read and write data by connecting to the master server or slave server. By reducing the load on the main server, system performance and reliability can be effectively improved.

3. Data synchronization technology

MySQL database distributed management technology needs to store data on multiple database servers, so data synchronization technology needs to be used for data synchronization. MySQL provides a variety of data synchronization methods, such as MySQL replication, MySQL Cluster, etc. In MySQL replication mode, one server acts as the master server and other servers act as slave servers. The master server copies data updates to the slave servers. In MySQL Cluster mode, multiple MySQL servers form a cluster, and each MySQL node has its own data. The advantage of this approach is that it greatly improves the reliability and fault tolerance of the system.

4. Load balancing technology

Load balancing technology is a commonly used database distributed management technology that achieves load balancing by allocating requests to different servers. MySQL supports a variety of load balancing technologies, such as using HAProxy for load balancing, using LVS for load balancing, and using DNS polling for load balancing. These technologies can distribute requests to different servers, thereby avoiding overloading a single server and improving the performance and scalability of the system.

To sum up, the database distributed management skills in MySQL provide us with efficient solutions and improve the performance and scalability of the system. By using these technologies, efficient storage and management of data can be achieved, and the reliability and fault tolerance of the system can be improved. In actual development, we should choose appropriate technical solutions and perform different configurations and optimizations according to business needs to obtain better results.
