> Support set cache strength for dict cache
> -----------------------------------------
>
> Key: KYLIN-4933
> URL: https://issues.apache.org/jira/browse/KYLIN-4933
> Project: Kylin
> Issue Type: Improvement
> Affects Versions: v3.1.1
> Reporter: ShengJun Zheng
> Assignee: ShengJun Zheng
> Priority: Major
> Fix For: v3.1.2
>
>
> 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.
