What changes were proposed in this pull request?
We have
DiskBalancerVolumeChoosingPolicy#chooseVolumeto choose a pair of {sourceVol, destVol}, and then haveContainerChoosingPolicy#chooseContainerto pick one container from sourceVol to destVol. In each function, overall ideal utilization and specific disk utilization are calculated individually to serve the logic.Consolidate two functions into one say,
DefaultVolumeContainerChoosingPolicywill avoid some recalculation.Another issue is that 5GB is used as the container size when choosing destVolume, while a specific container is picked, it's better for us to adjust destVolume's with container's real size, which could be larger than 5G, or less than 5G.
