  abstract: "As network infrastructures with 10 Gb/s bandwidth and beyond have become pervasive and as cost advantages of large commodity-machine clusters continue to increase, research and industry strive to exploit the available processing performance for large-scale database processing tasks. In this work we look at the use of high-speed networks for distributed join processing.  We propose Data Roundabout as a lightweight transport layer that uses Remote Direct Memory Access (RDMA) to gain access to the throughput opportunities in modern networks.  The essence of Data Roundabout is a ring-shaped network in which each host stores one portion of a large database instance.  We leverage the available bandwidth to (continuously) pump data through the high-speed network. Based on Data Roundabout, we demonstrate cyclo-join, which exploits the cycling flow of data to execute distributed joins.  The study uses different join algorithms (hash join and sort-merge join) to expose the pitfalls and the advantages of each algorithm in the data cycling arena. The experiments show the potential of a large distributed main-memory cache glued together with RDMA into a novel distributed database architecture. "

  abstract: "By leveraging modern networking hardware (RDMA-enabled network cards), we can shift priorities in distributed database processing significantly. Complex and sophisticated mechanisms to avoid network traffic can be replaced by a scheme that takes advantage of the bandwidth and low latency offered by such interconnects. We illustrate this phenomenon with cyclo-join, an efficient join algorithm based on continuously pumping data through a ring-structured network. Our approach is capable of exploiting the resources of all CPUs and distributed main-memory available in the network for processing queries of arbitrary shape and datasets of arbitrary size."
