I think this would be a useful abstraction. Eg maybe we could write directly to disk ... or, improve the RAM buffering to use growing/appending/paged buffers instead of one massive byte[] (which causes huge RAM spikes when we do ArrayUtil.grow) ... actually once we fix RAMFile it could just use that. > clean up FST storage abstractions > --------------------------------- > > Key: LUCENE-4593 > URL: https://issues.apache.org/jira/browse/LUCENE-4593 > Project: Lucene - Core > Issue Type: Bug > Reporter: Robert Muir > Attachments: LUCENE-4593.patch > > > I was looking at James patch for LUCENE-3298, and I thought that you know, FST *almost* abstracts its underlying "i/o" (storage) via reader/writer abstractions. > It would be good to try to work on this more, e.g. we can imagine a little abstraction like lucene has a Store (Directory). > This way maybe we could cleanup the packed vs non-packed, allow for > 2GB fsts without slowing down small ones, and so on. > I have a patch that is like an amoeba-step towards this -- This message is automatically generated by JIRA.
