Abstract

Current state-of-the-art parallel main memory DBMSs are designed according to the principles of a shared-nothing architecture driven by the intention of minimizing network traffic and thereby preserve the main memory performance advantage (as discussed in Chap. 2). The advent of RDMA-enabled network technology makes the creation of a parallel main memory DBMS based on a shared-storage technology feasible. A modern storage system such as RAMCloud keeps all data resident in main memory, provides durability, high-availability and is elastic: exploiting these characteristics in the context of a database management system is desirable. Nowadays, provisioning of information technology infrastructure over the Internet—including in-memory computing—allows the service providers to leverage the economies of scale and offer their services at an unbeatable price point. Being able to utilize hosted main memory-based storage for operating a database system makes in-memory data management even more economically viable.
