xiaotong2019 opened a new issue, #19847:
URL: https://github.com/apache/shardingsphere/issues/19847
## How can I use the VOLUME_RANGE algorithm type?
I am a novice user of the V5.1.2 framework and am currently encountering some confusion in usage.
When I read the document VOLUME_RANGE:
https://shardingsphere.apache.org/document/5.1.2/cn/user-manual/shardingsphere-jdbc/builtin-algorithm/sharding/
After that, the usage of the sample is not very familiar.
So, Pls help.. thanks.

Oh.., I found the cause of the problem, my sharding column cannot be the primary key, but should be other logical fields.
thanks.
