Subject [jira] [Commented] (HBASE-12217) Load based pushback for coprocessor invocations
Date Thu, 09 Oct 2014 18:09:36 GMT

Jesse Yates commented on HBASE-12217:
-------------------------------------

Linking this to the original client pushback jira where we wanted to slow dow the client if
the region is overloaded with writes (and gets blocked with compactions)

> 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.
