-------------------------------
Yes, it will also cause some problems like GC when the caching is improper.
It's hard to identified.

>
> As part of multi() request, RegionServer might receive requests with higher
> rows than row size threshold defined by hbase.rpc.rows.warning.threshold, and
> we provide warning log. To improve CPU consumption, we should introduce a
> config that would let RegionServer reject such requests other than providing
> warning log. This is an attempt to not let any client overburden CPU
> computation available to RegionServers.
