> 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.
