Subject [jira] Commented: (LUCENE-2504) sorting performance regression
Date Tue, 22 Jun 2010 15:16:58 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12881225#action_12881225
] 

Yonik Seeley commented on LUCENE-2504:
--------------------------------------

Hmmm, the way FieldComparator / FieldComparatorSource work now, it doesn't seem possible to
specialize based on the underlying native array type.  In order to do this, a new FieldComparator
would need to be returned for each segment.

One possibility: modify setNextReader to return a FieldComparator?
