> Kylin uses guava LoadingCache(LUR Cache) to cache dictionary with 
> soft(SoftReference) cache strength , it will be collected due to JVM GC. 
> In cases of queries over  dict-encoded-dimension cubes, we would always 
> prefer to cache dimension dictionary in LUR cache to avoid reloading dict 
> from HBase/HDFS, which will causes unstable query performance.
