------------------------------
Summary: Implement CLUSTER quota scope
Key: HBASE-21820
URL: https://issues.apache.org/jira/browse/HBASE-21820
Project: HBase
Issue Type: Sub-task
Reporter: Yi Mei
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 and region server quota, use [ClusterLimit /
RSNum] as machine limit. For table and user over table quota, use [ClusterLimit
/ TotalTableRegionNum * MachineTableRegionNum] as machine limit. Suggestions
are welcomed.
