Subject [jira] [Created] (LUCENE-3500) improve getLiveDocs() performance
Date Sat, 08 Oct 2011 14:20:29 GMT
improve getLiveDocs() performance
---------------------------------

                 Key: LUCENE-3500
                 URL: https://issues.apache.org/jira/browse/LUCENE-3500
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Yonik Seeley
            Priority: Minor


On segmentReader, liveDocs is volatile because they used to be loaded on demand.
This no longer appears to be the case... liveDocs are always loaded up front.
This also means that getLiveDocs() can never fail (even after close), and we can remove the
ensureOpen call.
Minor optimizations, but volatile reads still do prevent optimizations across that boundary.
