Clojure equivalent of Erlang DETS / Persistent-Maps

Question

I am looking for the Erlangs DETS equivalent for a permanent keystore / value store,
with the exception of the DETS 2G table size limit.

Berkeley DB Java Edition (with Clojure -wrapper available here ) is pretty nice. The core material is relatively simple, and if necessary, it supports replication and other high-availability features. It seems that the license is more like the GPL than the LGPL-like, so I think that for applications with closed source code (even without modifications to BDB JE itself) you will need a separate license.
