【 TiDB 使用环境`】
生产环境
【 TiDB 版本】
v5.2.2
【遇到的问题】
通过cdc同步到kafka,发现延迟很大,我们通过脚本把tiup ctl:v5.2.2 cdc changefeed list --pd=http://10.xx.xx.xx:2379的结果发送出来,下面是最近三天的情况
在6月2号10:00时,发现checkpoint是2022-06-02 06:14:52.968
在6月1号10:00时,发现checkpoint是2022-05-31 19:54:58.168
在5月31号10:00时,发现checkpoint是2022-05-31 01:03:39.369
【复现路径】做过哪些操作出现的问题
【问题现象及影响】
【附件】
附件是cdc.log与cdc_stderr.log

之前我也提过一个帖子,关于tso与checkpoint不变化的,说是可能是bug,但是我们版本已经是升级到v5.2.2了,帖子如下:
tidb 上是不是有大量的数据变更操作, 看下 cdc CPU 资源使用率是否很高。

这个帖子我也看过,不过我们已经是v5.2.2版本了。
看来是没有彻底解决,说是在5.3上会彻底解决
后面我们会有一次升级,到时候再观察观察。
谢谢了。
