Not a chance. Heaving large amount of files slows down write operations, as calling sync() on large number of files is slow. Also JDBM have very little redundancies, so risk of corruption of entire store is high, even with small data loss.

You may implement this on your own by extending 'Store'. It should be soon part of public API. But I will not integrate such patch.
