Perhaps the key can be modified only for comparation. You store the key as you want, but before compare it do a rle compression. You can store the rle compressed key in database too. Note that rle is a one-to- one transform, that is one key has only one compressed key and one compressed key has only one key. Working that way you can compare 200,1,1,2 with 199,1,2,2 (four bytes) instead 1111..(196 '1')..11112 with 1111..(195 '1')..111122.
