For improving space utilization, When node is splitted, then we have to
assign enteries to two groups. Once, one group is reached some threshod (m)
then, insert the remaining entries into another group.
Can you suggest some way to choose 'm' (beacuse cube store in form of NDBOX
that having variable length) or provide some guide with code?
Thanks
