Let's Talk About Storage & Recovery Methods for Non-Volatile Memory Database Systems
Joy James Prabhu Arulraj, Andrew Pavlo, Subramanya R. Dulloor · 2015
The advent of non-volatile memory (NVM) will fundamentally change the dichotomy between memory and durable storage in database management systems (DBMSs). These new NVM devices are almost as fast as DRAM, but all writes to it are potentially persistent even after power loss. Existing DBMSs are unable to take full advantage of this technology because their internal architectures are predicated on the assumption that memory is volatile. With NVM, many of the components of legacy DBMSs are unnecessary and will degrade the performance of data intensive applications.
