LRU policy, on heap - off heap size ?

Here is the my lru configuration

...
ccfg.setOnheapCacheEnabled(true);
ccfg.setEvictionPolicyFactory(new LruEvictionPolicyFactory<Integer,
Person>(2));
...

When I want to load 3 datas to cache, ignite console shows me

2 on heap and 3 off heap

why it is 2 on heap 1 off heap? Is it ignite features?

Hello,

Yep, it is expected behavior. You are using on-heap eviction policy and so,
this policy removes the cache entries from Java heap only. The entries
stored in the off-heap region of the memory are not affected.

Thanks.
