1 row in set (0.00 sec) 所以这种情况要把wait_timeout改大,再一个就是优化代码让sql跑快一点。 进程在server端被主动kill 这种情况和情况2相似,只是发起者是DBA或者其他job。发现有长时间的慢查询执行kill xxx导致。 $ mysql -uroot -p -e "show global status like 'com_kill'" ...

1 innodb_deadlock_detect 是检测死锁的一种方法,从mysql 5.7.13引入的, 在官方MYSQL 8.0 的文档中提到在高并发的系统中还是建议不使用 innodb_deadlock_detect. 大部分文字都在重复一个观点,高并发使用死锁的检测,会引起性能的问题 那么基本上每个文字都在描述打开这个开关会影响性能,到底影响那些性能了 ...
第一条 SQL 使用主键索引来查询,则只需要在 id = 49 这个主键索引上加上写锁;第二条 SQL 则使用二级索引来查询,则首先在 name = Tom 这个索引上加写锁,然后由于使用 InnoDB 二级索引还需再次根据主键索引查询,所以还需要在 id = 49 这个主键索引上加写锁,如上图所示。
