Comparison of database replication and synchronization mechanisms between MySQL and TiDB With the advent of the big data era, the amount of data continues to grow, and traditional database replication and synchronization mechanisms are inadequate in the face of high concurrency and large data volumes. In order to solve this problem, a new database system-TiDB has emerged, which is based on a distributed database architecture and can meet the storage and processing needs of massive data. This article will compare the database replication and synchronization mechanisms of MySQL and TiDB to discuss their advantages and disadvantages. 1. MySQL

MySQL semi-synchronous replication balances data consistency and performance by waiting for at least one slave library to confirm before the master library returns to the client. 1) Enable semi-synchronous replication on the main library: SETGLOBALrpl_semi_sync_master_enabled=1;2) Enable semi-synchronous replication on the slave library: SETGLOBALrpl_semi_sync_slave_enabled=1; This method not only improves data consistency, but does not seriously affect performance like synchronous replication.

How to set up highly available database replication on Linux Summary: In modern Internet applications, high availability of databases is very important, especially for key business scenarios such as online transactions and real-time data analysis. Database replication is a common way to achieve database high availability. This article will introduce how to set up highly available database replication on the Linux operating system to improve system availability and fault tolerance. Make sure the database server is configured correctly. Before you start setting up database replication, first make sure the database server is configured correctly.

There are three main ways of replication in MySQL: SBR, RBR and MBR. 1. SBR records SQL statements, which are suitable for standard operations, but may cause data inconsistency. 2. RBR records data changes to ensure consistency, but the log is large. 3.MBR combines the two and selects the method according to the SQL type, which is flexible but complex. Consistency, performance, and complexity are considered when choosing.

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

MySQL and Oracle: Comparison of database replication and synchronization functions [Introduction] In today's information age, data, as one of the important resources of enterprises and organizations, has attracted more and more attention. The replication and synchronization functions of the database are widely used in data backup, load balancing, disaster recovery, and synchronization of multiple data centers. As two mainstream relational database management systems, MySQL and Oracle have their own advantages and characteristics in database replication and synchronization. This article will focus on MySQL and Oracle

PHP and PDO: How to perform database table copying and migration When developing and maintaining applications, sometimes we need to perform database table copying and migration between different database environments. This may be because we need to deploy the application on a different server, or because we are upgrading or migrating the database. Whatever the case, using PHP and PDO (PHPDataObjects) is a convenient and flexible way to accomplish this task. First, let’s understand what PD is

How to design a highly available accounting system table structure in MySQL to ensure data reliability and availability? When designing a highly available accounting system table structure, we need to consider the reliability and availability of data. The following will introduce some methods for designing a highly available accounting system table structure in MySQL and provide corresponding code examples. Using Transactions Transactions are an important tool for ensuring data consistency and reliability. In the accounting system, various accounts, vouchers, transactions and other data need to ensure integrity and consistency. By using transactions,
