Realtime terms dictionary
-------------------------
Key: LUCENE-3245
URL: https://issues.apache.org/jira/browse/LUCENE-3245
Project: Lucene - Java
Issue Type: Improvement
Components: core/index
Affects Versions: 4.0
Reporter: Jason Rutherglen
Priority: Minor
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.
