Ryan McKinley commented on LUCENE-3354:
---------------------------------------

What are thoughts on using DocValues rather then FieldCache?

If we do choose to extend the FieldCache architecture, it would be so much 
cleaner if it were a simple Map<K,V> directly on the Reader rather then a 
static thing holding a WeakHashMap<Reader,Cache>
