[jira] [Created] (LUCENE-5683) Improve SegmentReader.getXXXDocValues

Shai Erera created LUCENE-5683:
----------------------------------

             Summary: Improve SegmentReader.getXXXDocValues
                 Key: LUCENE-5683
                 URL: https://issues.apache.org/jira/browse/LUCENE-5683
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Shai Erera
            Assignee: Shai Erera


Today we do two hash lookups, where in most cases a single one is enough. E.g. SR.getNumericDocValues initializes the FieldInfo (first lookup in FieldInfos), however if that field was already initialized, we can simply check dvFields.get(). This can be improved in all getXXXDocValues as well as getDocsWithField.
