greatsql 批量执行update指令时cpu利用率突然拉满
本帖最后由 紫川 于 2025-7-22 18:40 编辑你好，我请教你们一个问题，我们这边适配万里数据库的时候，程序批量执行update语句时会导致数据库的cpu利用率过高，其它select，insert都是正常的。我想请问下，你们又遇到过类似的问题没 （手动update就能复现）版本是：GreatSQL-8.0.32-25-Linux-glibc2.28-aarch64 请补充该表DDL以及相应的执行计划
另外，建议用最新的GreatSQL 8.0.32-27版本，而不是8.0.32-25版本哈 yejr 发表于 2025-7-23 10:23

不好意思，忘了提醒
执行计划麻烦改成 EXPLAIN SELECT这种风格的
另外，把my.cnf配置文件内容也贴一下
看你截图，UPDATE很快执行结束了，并没有被阻塞，可能是其他原因引起的CPU高
请补充提供 SHOW PROCESSLIST 和 SHOW ENGINE INNODB STATUS 的结果，如果可以也请补充 perf top 运行一二分钟后的结果 yejr 发表于 2025-7-23 10:37

你这是跑在虚机或容器中的吗，怀疑是虚机或容器方面的原因导致
另外，也有可能是在aarch64环境中部分版本的gcc编译器有问题导致，还请补充服务器运行环境以及GreatSQL是怎么编译的相关信息

是的，目前在用虚拟机测试，版本是这个GreatSQL-8.0.32-25-Linux-glibc2.28-aarch64，并没有编译 紫川 发表于 2025-7-23 14:04

你好，我们现在升级到最新版本，没这个问题了，都是虚拟机里
