Xiaoxiang Yu commented on KYLIN-4118:
-------------------------------------
SegmentCache won't be evict unless it has reach its TTL. Default of TTL is a
week(24 * 7 * 3600). Whether it is harmful should be decided by user, it is
regard as not a bug at the moment, so I will change the tag.
> SegmentQueryCache never evicted even it is useless

> In SegmentQueryCache.java, we find its evict method is never called, which
> seems to be unreasonable. SegmentQueryResult is often large, this may has
> risk to occupy too much space of memcached.
