---------------------------------
Summary: Move query cache back to query controller level
Key: KYLIN-1526
URL: https://issues.apache.org/jira/browse/KYLIN-1526
Project: Kylin
Issue Type: Improvement
Reporter: hongbin ma
Assignee: hongbin ma
from https://issues.apache.org/jira/browse/KYLIN-671,
https://issues.apache.org/jira/browse/KYLIN-836 we introduced a storage level
cache to take care of dynamic storages like Inverted Index (dynamic storage
keeps refreshing all the time)
however the II approach is not very popular since invented. And a storage level
cache is too heavy&complex and problematic(see
https://issues.apache.org/jira/browse/KYLIN-1522) for the more most commonly
used "static" cube storage engine. Thus I'd suggest to go back to before
KYLIN-671 and simply use a controller level cache.
