Jonathan Hsieh commented on HBASE-11048:
----------------------------------------

[~mbertozzi] should take a look -- he recently posted a design doc and some code for some
basic rpc scheduling for QoS purposes.

> Servers have the ability to handle custom rpc priority levels, but currently we are only
using it to differentiate META/ROOT updates from replication and other 'priority' updates
(as specified by annotation tags per RS method). 
> However, some clients need the ability to create custom handlers (e.g. PHOENIX-938) which
can really only be cleanly tied together to requests by the request priority. The disconnect
is in that there is no way for the client to overwrite the priority per table - the PayloadCarryingRpcController
will always just set priority per ROOT/META and otherwise just use the generic priority.
