Hmm, that's really interesting: hadn't thought of that.  I'll search the
archives if I get a chance.

I remember this coming up before...long causes thread saftey issues...

http://www.javaworld.com/javaworld/jw-09-1997/jw-09-raceconditions.html

I couldn't find anything on sun's java site to reference, but I didn't look
to hard.

Subject: doc number as integer


It seems that since the index document number value is a positive int, this
restricts the number of documents in an index to ( 2^31 - 1 ) =
2,147,483,647.

Do I misunderstand?

I mean, that's enough for me, but it seems a kind of surprising restriction,
considering long could be used instead for unimaginably large numbers of
documents.  Well, I grant I probably can't imagine 2 billion documents
either, but google can.

Just curious, sorry to bother anyone.
