-------------------------------------
Summary: Support set cache strength for dict cache
Key: KYLIN-4933
URL: https://issues.apache.org/jira/browse/KYLIN-4933
Project: Kylin
Issue Type: Improvement
Reporter: ShengJun Zheng
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.
