It looks good! One comment: it would be nice to add all possible suffixes
for each index type.

Common
BLOOM_FILTER_STRING = f

B-Tree
BTREE_STRING = b
BUDDY_BTREE_STRING = buddy

Inverted Index
DICT_BTREE_SUFFIX = b
INVLISTS_SUFFIX = i
DELETED_KEYS_BTREE_SUFFIX = d

R-Tree
RTREE_STRING = r
BTREE_STRING = b



Best,
Taewoo
