In MySQL, locks are the key mechanism to ensure concurrency control, data consistency, and transaction isolation. With the growth of database applications, how to efficiently manage concurrent operations has become a core issue in database performance optimization. MySQL provides a variety of lock mechanisms, including row locks and table locks, and implements the ACID characteristics of transactions through the close integration of lock mechanisms and indexes. In this article, we will explore in depth the implementation of MySQL locks, the difference between row locks and table locks, and the relationship between locks and indexes, to help developers...

In database development, transactions are one of the most important concepts, especially in scenarios with high concurrency and strict data consistency requirements. As a popular relational database, MySQL provides strong support for transactions, but many developers are not familiar with its implementation principles, design logic, and precautions in daily use. This article will deeply analyze the transaction implementation mechanism of MySQL, explain the four major characteristics of transactions and the problems they solve, analyze why MySQL is designed in this way, and propose some tips for developers to use transactions in their daily lives.
