Michael McCandless updated LUCENE-652:
--------------------------------------
Attachment: LUCENE-652.patch
I added o.a.l.document.CompressionTools, with static methods to
compress & decompress, and deprecated Field.Store.COMPRESS.
I also found two separate bugs:
* With Field.Store.COMPRESS we were running compression twice
(unnecessarily); I've fixed that.
* If you try to make a Field(byte[], int offset, int length,
Store.COMPRESS), you'll hit an AIOOBE. I think we don't need to
fix this one since it's in now-deprecated code, and with 2.9,
users can migrate to CompressionTools.
I plan to commit in a day or two.
> Compressed fields should be "externalized" (from Fields into Document)

> Key: LUCENE-652
> URL: https://issues.apache.org/jira/browse/LUCENE-652
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Index
> Affects Versions: 1.9, 2.0.0, 2.1
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 2.9

>
> Right now, as of 2.0 release, Lucene supports compressed stored fields.
> However, after discussion on java-dev, the suggestion arose, from Robert
> Engels, that it would be better if this logic were moved into the Document
> level. This way the indexing level just stores opaque binary fields, and
> then Document handles compress/uncompressing as needed.
> This approach would have prevented issues like LUCENE-629 because merging of
> segments would never need to decompress.
> See this thread for the recent discussion:
> http://www.gossamer-threads.com/lists/lucene/java-dev/38836
> When we do this we should also work on related issue LUCENE-648.
