There is some thing Wrong with the UseCase:
use client scan API : scan(prefix, null, _caching, new FilterList(new
PrefixFilter(prefix)));
i find if there is a Space at the prefix end,there may be has a big
filteredReadRequestCount in the regionserver which has the table region :

so when the request the get P99 may be has a high value:

so i want to know why a Space at the prefix end can cause this issue
