Summary: Load based pushback for coprocessor invocations
Key: HBASE-12217
URL: https://issues.apache.org/jira/browse/HBASE-12217
Project: HBase
Issue Type: New Feature
Reporter: Andrew Purtell
If a RegionServer host is already heavily loaded* then it might not be best to
accept more work in the form of coprocessor invocations. This could generalize
to all RPC work, perhaps as part of a broader admission control initiative, but
I think it makes sense to start small in an obvious place.
*: We could use % CPU utilization or the UNIX 1min or 5min load average to
determine this, and provide an option for choosing between those alternatives.
