STXXL equivalent in Java

Question

I'm searching a collection framework designed for huge datasets in Java that behaves transparently, like STXXL does for C++.

It should transparently swap to disk, but in a much more efficient manner than plain OS-based VM swapping. A StringBuffer/String drop-in replacement would be a big plus.

Answer 1

These fill needs only partially:

Oracle Berkeley DB Java Edition database backed collections: http://www.oracle.com/technology/documentation/berkeley-db/je/java/index.html

Joafip persistent collections: http://joafip.sourceforge.net/javadoc/net/sf/joafip/java/util/package-summary.html

Answer 2

Why not use a proper database?
