The space overhead is roughly constant (or at most logarithmic in n), and varies by the scheme. In practice, it’s something like 1.5-8x overhead. This is no big deal for storage, but does make it a pain on the memory side for processing (since the full database, including the overhead factor, needs to be resident in memory).
