Michael Busch commented on LUCENE-2324:
---------------------------------------
My last commit yesterday made almost all test cases pass.
The ones that test flush-by-ram are still failing. Also TestStressIndexing2
still fails. The reason has to do with how deletes are pushed into
bufferedDeletes. E.g. if I call addDocument() instead of updateDocument() in
TestStressIndexing.IndexerThread then the test passes.
I need to look more into that problem, but otherwise it's looking good and
we're pretty close!

> I'm copying here Mike's summary he posted on 2293:
> Change the approach for how we buffer in RAM to a more isolated
> approach, whereby IW has N fully independent RAM segments
> in-process and when a doc needs to be indexed it's added to one of
> them. Each segment would also write its own doc stores and
> "normal" segment merging (not the inefficient merge we now do on
> flush) would merge them. This should be a good simplification in
> the chain (eg maybe we can remove the *PerThread classes). The
> segments can flush independently, letting us make much better
> concurrent use of IO & CPU.
