Speedup merging of stored fields when field mapping "matches"
-------------------------------------------------------------

                 Key: LUCENE-1043
                 URL: https://issues.apache.org/jira/browse/LUCENE-1043
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
    Affects Versions: 2.2
            Reporter: Michael McCandless
            Assignee: Michael McCandless
            Priority: Minor
             Fix For: 2.3
         Attachments: LUCENE-1043.patch

Robert Engels suggested the following idea, here:

  http://www.gossamer-threads.com/lists/lucene/java-dev/54217

When merging in the stored fields from a segment, if the field name ->
number mapping is identical then we can simply bulk copy the entire
entry for the document rather than re-interpreting and then re-writing
the actual stored fields.

I've pulled the code from the above thread and got it working on the
current trunk.
