Hi Don't use JDBM if you want a BTree it is too slow... Been there.
Use Xindice's Filer class: org.apache.xindice.core.filer.Filer and
instantiate a org.apache.xindice.core.filer.BTreeFiler which is a whole lot
faster.
JDBM and Xindice are comparable in reading speed but surely not in writing.

Hmmm, I thought it did. Can't say I've studied the code though, so I'll
take your word for it.
Never mind on the Jackrabbit suggestion :-)

A possible open source solution using a page based database would be to
store the documents in http://jdbm.sourceforge.net/ which offers BTree,
Hash, and raw page based access. One would use a primary key type of
persistent ID to lookup the document data from JDBM.
Would be a good Lucene project
Hi John:

Hi All,
Thanks for all of the feedback. Largely as a result of the responses I've
received from the mailing list, Lucene has made it's way on to our short
list of possible solutions. I'm not sure what the timeframe is for
implementing a prototype and testing it, but I will try to report back wit
It surely is possible. AFAIK, LinkedIn use lucene to store some data.
But, Lucene index in a sense is similar to database index. Both are data
structures for a specialized and limited query execution path.
So this depends on your applications' query, and how you create the lucene
index. The norma
Yeah.. we do the same thing here for indexes of up to 57M documents
(rows), and that's just one part of our implementation.
It takes quite a bit of.. wrangling to use lucene in this manner.. but
we've found it to be utterly worthwhile.

I do this with uplib (http://uplib.parc.com/) with fair success.
Originally I thought I'd need Lucene plus a relational database to
store metadata about the documents for metadata searches. So far,
though, I've been able to store the metadata in Lucene and use the
same Lucene DB for both metadata
