Subject [jira] [Commented] (LUCENE-4515) Make MemoryIndex more memory efficient
Date Thu, 01 Nov 2012 12:51:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13488660#comment-13488660

Simon Willnauer commented on LUCENE-4515:
-----------------------------------------

bq. It should definitely be experimental. Tomorrow we might decide its cleaner to encode this
with RAMFile or something.
wait it's package private not protected so no need to annotate this really. We can change
as we want.

> 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.
