ZhouQianhao commented on KYLIN-928:
-----------------------------------
1. use LoadingCache(Guava) with expiration time and weakValues instead of
ConcurrentHashMap
2. move use DictionaryInfo.getCardinality() instead of Dictionary.getSize()
> Growing dictionary in streaming is potentially memory consuming for slowly
> increasing dictionaries
