Hi ??
(1) Cube merging will merge the files under ??cube_statistics?? directory of
the merging segments.
(2) ??cube_statistics?? save the cube's estimated information(like cuboid
rowcount, cuboid size), and it is used in many places, like spliting hbase
region, estimating the partition num in spark cubing. So you'd better not
delete it.
