![]() ![]() ![]() In this paper, we propose the concept of Distributed Data Persistency (DDP) model, which is the binding of the memory persistency model with the data consistency model in a distributed system. However, it is unclear how to tie NVM memory persistency models to the existing data consistency frameworks, and what are the durability guarantees that the combination will offer to distributed applications. In this environment, non-volatile memory (NVM) offers the ability to attain both high performance and data durability in distributed applications. ![]() Unfortunately, the reduced data durability guarantees provided can cause data loss or slow data recovery. They provide fault tolerance by replicating variables in the memories of different nodes, and using data consistency protocols to ensure consistency across replicas. Distributed applications such as key-value stores and databases avoid frequent writes to secondary storage devices to minimize performance degradation. ![]()
