Subject 回复: [KYLIN-1668] - Rowkey column shouldn’t allow delete and add
Date Fri, 15 Sep 2017 06:28:04 GMT
We have more dimensions, and can reach more than 20, so the number of region will be much larger,
and rowkey also accounts for a lot, so how to reduce the HBase region count?

Rowkey is the physical format of dimensions.
