             Summary: Use combined value to measure segment workload to improve the resource allocation strategy
                 Key: HAWQ-301
                 URL: https://issues.apache.org/jira/browse/HAWQ-301
             Project: Apache HAWQ
          Issue Type: Improvement
          Components: Resource Manager
            Reporter: Yi Jin
            Assignee: Lei Chang


In one segment, the combined workload counts:
1) total number of virtual segments allocated;
2) resource usage rate ( used/allocated );
3) estimated accumulated IO workload;

The new vsegs are allocated in the segments having lower combined workload. If data loclaity information is provided when one client requests query resource, the unbalance of number of vsegs among segments are restricted.
