[jira] [Created] (SOLR-5512) Optimize DocValuesFacets

Robert Muir created SOLR-5512:
---------------------------------

             Summary: Optimize DocValuesFacets 
                 Key: SOLR-5512
                 URL: https://issues.apache.org/jira/browse/SOLR-5512
             Project: Solr
          Issue Type: Improvement
            Reporter: Robert Muir


This works well in the general case (esp with huge numbers of unique values), but the SortedSetDocValuesAccumulator in lucene/facets does the algorithm better for typical cases (smaller number of unique values wrt the size of the document set).

In this case, it collects directly with per-segment local ords, then remaps as a second step. So this is a lot less remapping.

Its too bad the code is separate at the moment, for now lets steal the heuristic.
