Ma Gang commented on KYLIN-2899:
--------------------------------
By default, it will be closed, and open only all following conditions satisfied:
1. "kylin.query.segment-cache-enabled" config is set to true, it can be set in
cube level.
2. there is memcached configured in Kylin.
Segment level cache can improve query performance for the cube that is built
frequently, for example the streaming cube, the global cache will be
invalidated frequently.
> Enable segment level query cache
