Article Introduction：How to understand and apply the MySQLMVCC principle Introduction: MySQL is a commonly used relational database management system, which uses the MVCC (Multi-VersionConcurrencyControl) principle to ensure data consistency and concurrency. MVCC is a transaction concurrency control method that implements read and write operations on data based on version management. This article will introduce the basic concepts of MVCC principles and how to apply MVCC in MySQL. 1. MVCC original

Article Introduction：1. Overview: MVCC, the full name is Multi-VersionConcurrencyControl, which is multi-version concurrency control. MVCC is a multi-concurrency control method. It is generally used in database management systems to achieve concurrent access to the database and to implement transactional memory in programming languages. We know that MySql changed from MyISAM storage engine to InnoDB storage engine after 5.5, mainly because InnoDB supports transactions, so when multiple threads are executed at the same time, concurrency problems may occur. At this time, a method that can control concurrency may appear, and MVCC plays this role. MVCC mainly relies on undolog version chain and ReadView to implement
