Hi,
> When I get the map with store.openMap("name map") I see that all the
objects are built, auto vivification, like in Perl.
Opening the map will not read all entries of the map from disk. It might
read a few entries (the root page of the b-tree), but that's about it. Even
if you call map.get() for each entry, it will not keep all entries in
memory; only the most commonly used ones are kept in memory at any time
(using a LIRS cache).
I don't think this is related to auto vivification in Perl.

That's not a problem.
