Offheap mode mostly refers to the way the cache entries are stored. There are many other parts of the product that rely on the Java heap like any Java application. In case of a node joining/leaving a topology, partition rebalancing process will take place, which
inevitably will affect heap.

As per my understanding by default ignite 2.0 keeps all objects in off heap by default
We have kept java heap as 8 GB for all machines in cluster
1. When we add or remove a node (Partitioned cached, with backup one) we see that heap usage in one machine of cluster accordingly decreased and increased.
Ideally if off heap is used, heap usage should not fluctuate when we add/remove nodes in cluster
