I ran into troubles with OutOfMemory error while all caches are being stored in off-heap memory. After memory dump profiling I figured out that heap memory was allocated for:
1. org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtLocalPartition (50% of heap)
2. Pointers to unasfe off heap memory are stored in the heap.
The second case is clear. But what about the first one? What are the objects of org.apache.ignite.internal.processors.cache.distributed.dht.GridDhtLocalPartition created for? Is there a way to tune it? I noticed that some binary data is stored inside them.
