Gaofei Cao commented on IOTDB-4897:
-----------------------------------
This pr (https://github.com/apache/iotdb/pull/8140) added double keysort.
# First key: select the DataNode that currently has the minimum number of
Regions.
# Second key: select the DataNode that currently has the maximum free disk
space.
We can test it in real environment if it works.
> [Design] DataRegion Load balance based on Disk Usage
