Subject [jira] [Updated] (LUCENE-3245) Realtime terms dictionary
Date Mon, 27 Jun 2011 05:48:47 GMT


Jason Rutherglen updated LUCENE-3245:

    Attachment: LUCENE-3245.patch

Added and fixed the code that traverses the skip list to the level zero linked list and iterates.

I need to reuse the starts int array, that's next.

> For LUCENE-2312 we need a realtime terms dictionary.  While ConcurrentSkipListMap may
be used, it has drawbacks in terms of high object overhead which can impact GC collection
times and heap memory usage.  
> If we implement a skip list that uses primitive backing arrays, we can hopefully have
a data structure that is [as] fast and memory efficient.
