    Description

      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.
