I-Store: Data Management on Fast Networks

The next generation of high-performance RDMA-capable networks requires a fundamental rethinking of the design of modern distributed in-memory DBMSs. These systems are commonly designed under the assumption that the network is the bottleneck and thus must be avoided as much as possible. This assumption no longer holds true. With InfiniBand FDR 4x, the bandwidth available to transfer data across the network is in the same ballpark as the bandwidth of one memory channel, and the bandwidth increases even more with the most recent EDR standard. Moreover, with increasing advances in RDMA, transfer latencies improve similarly fast.

In this project, we first argue that the “old” distributed database design is not capable of taking full advantage of fast networks and suggest a new architecture. Second, we discuss initial results of a prototype implementation of this architecture for OLTP and OLAP, and show remarkable performance improvements over existing designs.
