Note that the internal structure of each DB that needs to access etherogeneous data in a *fast* way it is not necessarily space-optimized. So, if you add-remove-substitute keys with data having different content length, the db continues to grow, wasting space. So, it is necessary, sometimes, to re-pack the db in order to remove unused data from the db itself. But it is important to remind that, even if the file grows, the data remain optimized and - obviously - the access continues to be fast.
