> In a large cluster, with a large number of clients, we found the RS's
> handlers are all busy sometimes. And after investigation we found the root
> cause is about CSLM, such as compare function heavy load. We reviewed the
> related WALs, and found that there were many columns (more than 1000 columns)
> were writing at that time.
