First, we have a table a with the following structure:
Then we made some operations on it, as shown below:
Suppose these operations are performed at 16:20:00? The operation is performed within 16:21:00 on January 25. It was also operated in a later period.
Now we want to see at 16:20:00? The operation content within 16:21:00 a.m. on February 25.
The recovered database is as follows:
In this way, we can observe the change process of the num column with id = 1 in table.
Typical scenario: good

Newlisp tracks jobtracker status, newlispjobtracker

Each time the status data is obtained, it is stored in the mysql database, and tableau is used to present the status of the mapreduce cluster with reports.
This is the data of the jobtracker site.
This is a report draw
