Hi. I have actually created a solution where I use Lucene as Tuple (key/value) storage. It was surprisingly fast and it has more balanced read/write performance compared to BTrees but I think it is a little slower in retrieving value per key than a Tree.
Look here for hints: http://dev.tailsweep.com/svn/abstractcache/trunk/src/main/java/org/tailsweep/abstractcache/disk/lucene/LuceneCache.java Kindly //Marcus On Thu, Jul 31, 2008 at 4:46 PM, Andy Liu <[EMAIL PROTECTED]> wrote: > If essentially all you need is key-value storage, Berkeley DB for Java > works > well.
