JDBCDirectory to prevent optimize()?
It seems that when compared to other datastores that Lucene starts to
fall down. For example lucene doesn't perform online index
optimizations so if you add 10 documents you have to run optimize()
again and this isn't exactly a fast operation.
I'm wondering about the potential for a generic JDBCDirectory for
keeping the lucene index within a database.
It sounds somewhat unconventional would allow you to perform live
addDirectory updates without performing an optimize() again.
Has anyone looked at this? How practical would it be.

Such a thing already exists: http://ppinew.mnis.com/jdbcdirectory/, but I
don't know about its scalability.

Huh? Why would you assume that? As far as I know, and I've tested
this some, a Lucene index inside Berkeley DB works the same as if it
had been in RAM or on the filesystem.

I assume this would prevent prefix queries from working...

Also, there is a DBDirectory in the sandbox to store a Lucene index
inside Berkeley DB.
