MySql locks and transactions: How to quickly implement MySQL concurrency control and lock mechanism
Article Introduction:MySQL is a widely used open source relational database management system and has been widely used in enterprise-level applications. In high-concurrency application scenarios, MySQL's concurrency control and locking mechanism are particularly important. This article will explore how to use MySQL's transaction and lock mechanism to quickly implement concurrency control. 1. Introduction to MySQL locks and transactions MySQL locks and transactions are very important because in the case of multiple users, MySQL must support multiple concurrent operations at the same time. This requires MySQL to use locks to control concurrent access

Detailed explanation of concurrency control of distributed transactions implemented by Redis
Article Introduction:With the development of Internet applications, distributed systems have become an inevitable trend. In a distributed system, data interaction is required between multiple services, and these data interactions can be viewed as a series of transactions. When multiple services operate on transactions at the same time, concurrency control is required. Redis is a high-performance key-value database that is widely used in distributed systems. It supports a variety of data structures and commands, including transactions and monitoring, making it a good choice for concurrency control in distributed systems. This article will introduce R in detail
