Hi John, Could you please re-phrase you question. What issue are you trying to solve?
Probably, you should address your question directly to dev-list. Anyway, you can read about memory region architecture at [1] and [2]. Hope it helps.

Hi, I was looking at the UnsafeMemoryProvide and it looks to me that allocated direct memory regions are deallocated only during shutdown. https://github.com/apache/ignite/blob/c5a04da7103701d4ee95910d90ba786a6ea5750b/modules/core/src/main/java/org/apache/ignite/internal/mem/unsafe/UnsafeMemoryProvider.java#L80 https://github.com/apache/ignite/blob/c5a04da7103701d4ee95910d90ba786a6ea5750b/modules/core/src/main/java/org/apache/ignite/internal/mem/unsafe/UnsafeMemoryProvider.java#L63 My question: if a memory region has been allocated and, during execution, all data pages that are in the region are removed, then why is the memory region de-allocated? Thanks,
