> 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.
