   Today, another cluster of ours (without any modification) once again 
experienced the problem that the expired data of the hot node was not deleted, 
causing the storage space to be quickly used up.

   It looks like the storage space of the hot node is almost full, and the cold 
node still has enough storage space.

   Here are some monitoring:

   After this problem occurred, I quickly emitted the monitoring data to 
promethues. After observing for two hours, I upgraded the master node and 
applied `LoadDropByPeriod`, and the cluster quickly returned to normal. Of 
course, our cluster also found some problems in the process of applying 
`LoadDropByPeriod`, such as the need to limit the speed of deletion.
   
   
   I still have a few hours of monitoring data on my side that I can share with 
you if you need it. @kfaraz
