Jason Rutherglen commented on LUCENE-1313:
------------------------------------------
{quote}doc store files punch straight through to the real
directory{quote}
To implement this functionality in parallel (and perhaps make
the overall patch cleaner), writing doc stores directly to a
separate directory can be a different patch? There can be an
option IW.setDocStoresDirectory(Directory) that the patch
implements? Then some unit tests that are separate from the near
realtime portion.

> Realtime search with transactional semantics.
> Possible future directions:
> * Optimistic concurrency
> * Replication
> Encoding each transaction into a set of bytes by writing to a RAMDirectory
> enables replication. It is difficult to replicate using other methods
> because while the document may easily be serialized, the analyzer cannot.
> I think this issue can hold realtime benchmarks which include indexing and
> searching concurrently.
