[jira] [Created] (LUCENE-6133) improve default stored fields merge algorithm

Robert Muir created LUCENE-6133:
-----------------------------------

             Summary: improve default stored fields merge algorithm
                 Key: LUCENE-6133
                 URL: https://issues.apache.org/jira/browse/LUCENE-6133
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Robert Muir


This is not very efficient today. 

We should try to improve the default one and not rely so much upon bulk merges. At the least we can use a specialized visitor, save some cpu, and avoid creating so much garbage.

Another pain point in default merge is all the string creation and unicode encode/decoding back and forth. I don't tackle that here... but that would be fantastic to fix in another issue.
