The problem of data integration has been around for decades, yet a satisfactory solution has not yet emerged. A new type of system called a polystore has surfaced to partially address the integration problem. Based on experience with our own polystore called Big-DAWG, we identify three major roadblocks to an acceptable commercial solution. We offer a new architecture inspired by these three problems that trades some generality for usability. This architecture also exploits modern hardware (i.e., high-speed networks and RDMA) to gain performance. The paper concludes with some promising experimental results.
