Efficient Durability Support for Multicore In-Memory Database

The increasing core counts and memory volume open opportunities to perform online transactional processing (OLTP) in memory, leading to a new type of databases, called in-memory databases. However, this also makes durability and failure recovery a critical issue due to the volatility of main memory. In this paper, we describe the design and implementation of Gawain, which provides both efficient logging and fast recovery for in-memory databases
