Subject [jira] Commented: (LUCENE-1410) PFOR implementation
Date Tue, 21 Dec 2010 21:28:04 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12973897#action_12973897
] 

Paul Elschot commented on LUCENE-1410:
--------------------------------------

I'm running into a nocommit for the nio byte buffer allocation in ForDecompress.java.
Shall I try and move the buffer handling from there into FORIndexInput and PForDeltaIndexInput
at the codecs?
I could leave it as it is, but then the test cases from the 1410e patch would have to be adapted
again when the nocommit is fixed.

Also the package/directory naming o.a.l.util.pfor and o.a.l.index.codecs.pfordelta may be
confusing.
Probably pfordelta could could be renamed to pfor, since delta refers to differences (in docids
and positions) that are treated elsewhere.
But I'd rather not change that now.
