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 : !image-2021-03-08-13-37-40-574.png! so when the request the get P99 may be has a high value: !image-2021-03-08-13-40-06-900.png! so i want to know why a Space at the prefix end can cause this issue -- This message was sent by Atlassian Jira (v8.3.4#803005)
