>
> 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.
