MyISAM 存储引擎在以读取为主的数据或低并发操作中表现最佳，因为表锁限制了同时执行更新的能力。在 MySQL 中，InnoDB 是默认的存储引擎，而不是 MyISAM。The MyISAM storage engine performs best with read-mostly data or with low-concurrency operations, because table locks limit the ability to perform simultaneous updates. In MySQL, InnoDB is the default storage engine rather than MyISAM.
