    Description

      There are several ways to reduce memory footprint of DiffListBySkipList.

      • Move maxSkipLevels and skipInterval to DirectoryDiffListFactory.
      • Use an array for skipDiffList instead of List.
      • Do not store the level 0 element in skipDiffList.
      • Do not create new ChildrenDiff for the same value.
