> There are two kinds of quota scope: CLUSTER and MACHINE. CLUSTER quota means
> quota limit is shared by all machines of cluster. MACHINE quota means quota
> limit is used by single region server.
> Currently, all set quota operations use MACHINE scope as default and CLUSTER
> scope has not been implemented. So open this issue to implement CLUSTER quota
> scope.
> To split cluster quota limit to machines, the basic idea is for user,
> namespace, user over namespace quota, use [ClusterLimit / RSNum] as machine
> limit. For table and user over table quota, use [ClusterLimit /
> TotalTableRegionNum * MachineTableRegionNum] as machine limit. Suggestions
> are welcomed.
