Description
Quotas only support soft limits. Previously, some limits have accidentally been overly strict in a way that caused difficult UX, and we made them more lenient in https://issues.apache.org/jira/browse/HBASE-28672
It would be nice if quotas allowed users to specify hard throughput limits that they would certainly not exceed. This would be simple for read/write/request number quotas, but would be more difficult for read size throttling where workload estimations are much less precise. It's possible that this can/should only be supported for some combination of read number, write number, request number, and write size throttles.
