----------------------------------
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.
