   InventoryDataScalingTask serial execute in the InventoryDataScalingTaskGroup, and conurrency execute between InventoryDataScalingTaskGroup.

   I think this is a bug. Because in 4.1.1 ScalingTask can  parallel execute in TaskGroup. We actually want to do it in parallel as well. Otherwise,InventoryDataScalingTaskGroup doesn't make any difference. just can remove  InventoryDataScalingTaskGroup only use InventoryDataScalingTask.
