--------------------------------------------------------------
Comments for the HIVE-18056.1.patch:
1. Can you put a note how this comma separated list look like (db.table) by
giving an example, also what happen when a table appear in both blacklist and
whitelist?
2. I assume capture exception during prewarm (such as table is dropped during
prewarm, no need to interrupt prewarm) will be in a separate Jira, is that
right?
3. getDatabases, we shall get from db if prewarm is not done, rather than wait
4. getAllTables/getTableMeta/listTableNamesByFilter, if both black/white list
are empty, we can get from cache
5. Why we don't handle get_aggr_stats_for with cache?

> CachedStore: Have a whitelist/blacklist config to allow selective caching of
