Hello Ignite-Community! I just found IGNITE-3477 and esp.
"Continuous put/remove operations with OFFHEAP_TIERED mode lead to uncontrollable memory fragmentation" How does Ignite handle OFFHEAP_TIERED caches currently (= how does it store the data)? I just tried to create some tests to get an impression of the fragmentation, however, I couldn't see a huge issue. In my case I've 30gb Offheap memory available and about 5 caches storing about 3gb of data (after starting the application). Every entry of the caches gets updated every few days the latest and some several times a day. However, I would like to avoid that cache-fragmentation hits the application out of the blue and therefore I try to get an impression about those internals. Any hint is appreciated, Peter
