                p 100% of data is persisted to Ignite native persistence, and the same or smaller amount is cached in memory. The more data cached, the faster the performance.
                p Applications can query both in-memory and disk-only records transparently scaling beyond available memory capacity.
                p There is no need for memory warm-ups on restarts since Ignite can serve data from disk. SSD, Flash, HDD or Intel® Optane™ operating in the AppDirect Mode can be used as a storage device.
