Describe a modified version of the B-tree insertion algorithm so that each time we create an overflow because of a split of a node w, we redistribute keys among all of w’s siblings, so that each sibling holds roughly the same number of keys (possibly cascading the split up to the parent of w). What is theminimumfraction of each block that will always be filled using this scheme?
