Subject [jira] [Created] (LUCENE-4515) Make MemoryIndex more memory efficient
Date Wed, 31 Oct 2012 11:49:11 GMT
Simon Willnauer created LUCENE-4515:

             Summary: Make MemoryIndex more memory efficient
                 Key: LUCENE-4515
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/other
    Affects Versions: 4.0, 4.1, 5.0
            Reporter: Simon Willnauer
             Fix For: 4.1, 5.0

Currently MemoryIndex uses BytesRef objects to represent terms and holds an int[] per term
per field to represent postings. For highlighting this creates a ton of objects for each search
that 1. need to be GCed and 2. can't be reused.
