First, we use double write mode benchmark to write out of order data into IoTDB
0.12.5 and IoTDB 0.13.0, related benchmark config:
write-config.properties(please modify host).
then, we use double point check mode benchmark to check the data between them,
related benchmark config: check-config.properties.
And we find there are something wrong happen in benchmark log:
!image-2022-01-30-16-24-45-709.png!
After that, we try to find what's wrong of d_1 in this time, use
`./export-csv.sh -h 127.0.0.1 -p 6667 -u root -pw root -td /home/xzh -q "select
* from root.test.g_0.d_0 where time >= 1541390305000 and time < 1541390805000
order by time desc"` to export data. The data of IoTDB 0.12.5 is 12.5.csv, and
the data of IoTDB 0.13.0 is 13.0.csv.
Then we compare them and find there are differences:
!image-2022-01-30-16-29-41-688.png!
!image-2022-01-30-16-30-25-700.png!
It looks like that some line in 0.12.5 has been splited into 2 line in 0.13.0.
