Subject [jira] [Commented] (LUCENE-3892) Add a useful intblock postings format (eg, FOR, PFOR, PFORDelta, Simple9/16/64, etc.)
Date Wed, 11 Jul 2012 13:58:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13411515#comment-13411515
] 

Michael McCandless commented on LUCENE-3892:
--------------------------------------------

bq. Not my idea actually, I think the exception should be thrown for out.close()? closeWhileHandlingException()
will suppress those exceptions

But the problem is some other exception has already been thrown (because success is false).
 If out.close then hits a second exception we have to pick which one should be thrown, and
I think the original one is better?  (Since it's likely the root cause of whatever went wrong).

> On the flex branch we explored a number of possible intblock
> encodings, but for whatever reason never brought them to completion.
> There are still a number of issues opened with patches in different
> states.
> Initial results (based on prototype) were excellent (see
> http://blog.mikemccandless.com/2010/08/lucene-performance-with-pfordelta-codec.html

> I think this would make a good GSoC project.
