Long story short, the 'Durable' memory is a page based memory architecture that is split into pages of fixed size. Ignite 'Native persistence' is a feature provided by Ignite and which allows storing your data on disk. Please take a look at the following pages [1] & [2] > 3.

Yes, that is correct as long as you have free space on disk, of course. > 4 How to check if the read happened from ignite persistence(disk) or > memory? There is no such capability if I am not mistaken.
