It is off heap tiered with max off heap of 40gb or so and in some cases, 0 (no limit) No eviction policy, by default will be LRU?
Wondering internal datastructures shall not cause such large heap growth, unless there is a lag from on heap to off heap On Sep 12, 2016 5:23 AM, "Andrey Gura" <[email protected]> wrote: > Hi, > > what cache model do you use?
