Polystore++: Accelerated Polystore System for Heterogeneous Workloads

Abstract

Modern real-time business analytic consist of heterogeneous workloads (e.g., database queries, graph processing, and machine learning). These analytic applications need programming environments that can capture all aspects of the constituent workloads (including data models they work on and movement of data across processing engines). Polystore systems suit such applications; however, these systems currently execute on CPUs and the slowdown of Moore's Law means they cannot meet the performance and efficiency requirements of modern workloads. We envision Polystore++, an architecture to accelerate existing polystore systems using hardware accelerators (e.g., FPGAs, CGRAs, and GPUs). Polystore++ systems can achieve high performance at low power by identifying and offloading components of a polystore system that are amenable to acceleration using specialized hardware. Building a Polystore++ system is challenging and introduces new research problems motivated by the use of hardware accelerators (e.g., optimizing and mapping query plans across heterogeneous computing units and exploiting hardware pipelining and parallelism to improve performance). In this paper, we discuss these challenges in detail and list possible approaches to address these problems.

Improving Interoperability between Relational and Blockchain-based Database Systems: A Middleware approach

“…On the other hand, Polyphony-DB [Vogt et al 2018] conceptualizes a selfadaptive system with data replication and partitioning. [Singhal et al 2019] also presents the building blocks of Polystore++, which envisions a highly performance-oriented polystore solution.…”

J-CO: A Platform-Independent Framework for Managing Geo-Referenced JSON Data Sets

“…It appears that BigDAWG [38] is the first polystore system in the literature; nevertheless, it is not an isolated case and the work on polystores is going on. For example, [39] reports about Polystore++, a polystore system for analytic applications. However, the definition of polystore systems requires the development of techniques for building query plans (as in [40]), as well as to define extensions of the classical relational algebra (as in [41]).…”
