in particular in cloud environment (with typically 3 AZs that one at a time may experience large scale events or failures) or other situations with few large racks that one need to handle as a failure mode without data loss the memory consumption for "backup count" is significant and it would be a good option to be able to store this data on a flash based (or for instance off-heap) structure (both options for instance provided by Chronicle Map so perhaps a usable component ro base an implementation on)
