---------------------------

测试环境在192.168.10.72/73/74  /data/mpp_test/t_m_1024_77ea964
benchmark在192.168.10.71 /home/liuzhen/benchmark/bm_2023_0609_f235604/conf
副本间数据依然有不一致的现象
本次benchmark测试结果:

>          Issue Type: Bug
>          Components: mpp-cluster
>    Affects Versions: 1.1.0-SNAPSHOT
>            Reporter: 刘珍

> 测试版本:rc/1.1.0 0306_32f9db0
> 1.关合并,启动3副本3C3D
> dn_metric_internal_reporter_type=IOTDB 开启数据库统计写入历史点数
> 2.启动benchmark执行写入与查询,运行24小时。
> 3.(24小时后)cli执行flush
> 4. 对比系统库记录的写入点数,与bm结果:
> bm okPoint:187183800000
> IoTDB:561244290000 (见下图),561244290000 /187183800000= 2.9983593131456887
> {color:red}*各节点数据不一致。*{color}
>  !image-2023-03-20-14-09-43-058.png! 
> 另外的一种方法也可以验证各节点数据的一致性:
> ~ 3个节点在线,查询:
> "select min_time(s_9),max_time(s_9),count(s_9) from root.** align by device"
> 记作q1,
> ~ stop ip66/ip68,只有ip62在线,执行相同查询,记作q2
> ~ stop ip62/ip68,只有ip66在线,执行相同查询,记作q3
> ~ stop ip62/ip66,只有ip68在线,执行相同查询,记作q4
> q1和q2/q3/q4预期结果一致,实际q2和q1就不一致,不需要执行后续的q3和q4.
