> Key: KYLIN-4012
> URL: https://issues.apache.org/jira/browse/KYLIN-4012
> Project: Kylin
> Issue Type: Improvement
> Affects Versions: v2.5.0
> Reporter: jiezouSH
> Assignee: jiezouSH
> Priority: Major
> Fix For: v3.0.0-alpha2
>
>
> Currently,
> CacheDictionary, parent class of TrieDictionary and TrieDictionaryForest, has 3 cache:
> valueToIdCache,
> idToValueCache,
> idToValueByteCache.
> However, The function of idToValueCache and idToValueByteCache is highly duplicated.
> It is better to merge idToValueCache and idToValueByteCache, saving memory in about half the dict's physical size
