[jira] [Created] (LUCENE-6630) Further improve memory of FieldInfos

Ryan Ernst created LUCENE-6630:
----------------------------------

             Summary: Further improve memory of FieldInfos
                 Key: LUCENE-6630
                 URL: https://issues.apache.org/jira/browse/LUCENE-6630
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Ryan Ernst


In LUCENE-6325, FieldInfos were improved to use an array except in very sparse cases. In the sparse cases, a TreeMap is still used. However, even in the sparse case, we can still use an array, and then use binary search. The perf will be equivalent, but memory use should be much less.
