Building Efficient Query Engines using High-Level Languages

We are currently witnessing a shift towards the use of high-level programming languages for systems development. These approaches collide with the traditional wisdom which calls for using low-level languages for building efficient software systems. This sh ...

How to Architect a Query Compiler

Lewis Alexander Brown, Christoph Koch, Amir Shaikhha, Ioannis Klonatos, Mohammad Dashti Rahmat Abadi, Lionel Emile Vincent Parreaux

This paper studies architecting query compilers. The state of the art in query compiler construction is lagging behind that in the compilers field. We attempt to remedy this by exploring the key causes of technical challenges in need of well founded soluti ...

Building Efficient Query Engines in a High-Level Language

Tiark Rompf, Christoph Koch, Ioannis Klonatos, Hassan Chafi

In this paper we advocate that it is time for a radical rethinking of database systems design. Developers should be able to leverage high-level programming languages without having to pay a price in efficiency. To realize our vision of abstraction without ...

Automatic Synthesis of Out-of-Core Algorithms

Viktor Kuncak, Andres Nötzli, Andrej Spielmann, Christoph Koch, Ioannis Klonatos

We present a system for the automatic synthesis of efficient algorithms specialized for a particular memory hierarchy and a set of storage devices. The developer provides two independent inputs: 1) an algorithm that ignores memory hierarchy and external st ...
