What's the reason because it needs so many space Ignite to store data in memory?. For example, if your dataset it's about 4TB and you are going to use backup (1 replica) the final size it's about
5TBx2.5x1.3(indices) x backcup = 26TB more or less... So, it could be 28TB with the memory of the system to work. It seems insane to have that memory in many cases. How does Ignite store data to spend 3 times the size on disk? is it possible to reduce this?
