Jason Rutherglen updated LUCENE-1313:
-------------------------------------
Attachment: LUCENE-1313.patch
Patch is updated to trunk and compiles. Unit tests fail because
they're hardcoded for specific numbers of files etc, otherwise I
don't think there's anything glaring.
The included benchmark indexes 1 document, queries with a sort,
and repeats N times. This is way too taxing using the existing
IW.getReader when pointing to a hard drive, basically the
machine becomes unusable. I haven't figured out what to publish
or how long I want to wait. I'll just run it overnight.
This patch's benchmark fairs much better, I'll publish it's
results as well. Thinking 1, 10, 25, 50, 100, 1000 doc
increments should suffice, so there's some variation.

> Enable near realtime search in Lucene without external
> dependencies. When RAM NRT is enabled, the implementation adds a
> RAMDirectory to IndexWriter. Flushes go to the ramdir unless
> there is no available space. Merges are completed in the ram
> dir until there is no more available ram.
> IW.optimize and IW.commit flush the ramdir to the primary
> directory, all other operations try to keep segments in ram
> until there is no more space.
