Antal Sinkovits commented on HIVE-20440:
----------------------------------------
(1) I think because of the soft values, the GC decides when to clean up them.
(When it needs more memory)
(2) AFAIK we can use them together, but it won't stop the GC from clearing the
values.
> Create better cache eviction policy for SmallTableCache
