[2483cebd7950f3bec709fb35a047f67] 国产化顺势而行

[quote=“TiDBer_yanggui, post:9, topic:1038797”] 你们有国产化改造的需求吗？】无 【聊聊你们认为国产化改造、国产数据库替换的真实收益】 支持国产化

TICDC目前支持那种语言二开

操作系统限制tidb使用资源

看一下sql执行计划

表里面字段类型太短了吧可以调长试试

很有可能慢sql查询热点表导致IO占用很高

考虑性能的原因，怕会影响服务器性能

试试这个语句 UPDATE mysql.user SET account_locked = ‘Y’ WHERE user = ‘username’ AND host = ‘host’;

检查网络和io看一下有没有异常

建议看看官方文档
