MySQL InnoDB是如何实现ACID的？

The ACID model is a set of database design principles that emphasize aspects of reliability that are important for business data and mission-critical applications. MySQL includes components such as the InnoDB storage engine that adhere closely to the ACID model so that data is not corrupted and results are not distorted by exceptional conditions such as software crashes and hardware malfunctions. When you rely on ACID-compliant features, you do not need to reinvent the wheel of consistency checking and crash recovery mechanisms. In cases where you have additional software safeguards, ultra-reliable hardware, or an application that can tolerate a small amount of data loss or inconsistency, you can adjust MySQL settings to trade some of the ACID reliability for greater performance or throughput.

ACID 模型是一组数据库设计原则，强调对于业务数据和关键任务应用程序而言重要的可靠性方面。MySQL 包括诸如 InnoDB 存储引擎等组件，严格遵循 ACID 模型，以确保数据不会因软件崩溃和硬件故障等异常情况而损坏，
