[jira] [Updated] (HBASE-12731) Heap occupancy based client pushback
[ https://issues.apache.org/jira/browse/HBASE-12731?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Purtell updated HBASE-12731:
-----------------------------------
Description:
If the heap occupancy of a RegionServer is beyond a configurable high water mark (suggestions: 95%, 98%) then we should reject all user RPCs and only allow administrative RPCs until occupancy has dropped below a configurable low water mark (suggestions: 92%).
Implement building on the HBASE-5162 changes.
It might be expensive to check heap occupancy, in which case we can sample it periodically with a chore and use the last known value in pushback calculations.
