Hi Dmitriy

Could you explain what is the difference between:
- disk is a copy of the memory (only for recovery purposes)
- disk is a data storage with memory used as a performant caching layer

I assume it is all about DataRegionConfiguration.setPersistenceEnabled and
there is no other options I can imagine.

Could you refer to options for cases 2 & 3 user should enable to cover
these 2 cases.

Sincerely,
Dmitriy Pavlov
