Continuous Intelligence through Computation Sharing with Arcon

Abstract

There is high diversity today in the ways people can declare and execute computations on high volumes of data. Each available framework focuses on compiling and executing functions with a specific data model in mind (e.g., data frames, tensors, streams, graphs etc.) and often supporting a single programming language (e.g., python or scala). Critical performance and operational issues though arise when analytics teams try to put all these pieces of software together in order to build end-to-end pipelines. This hinders the use of data-driven insights for critical decision making. To that end, we investigate a fundamental solution to this problem that is computation sharing across frameworks, at the instruction level. Arcon, is a system we currently build at RISE and KTH that provides this opportunity. At its core, Arcon is equipped with a powerful compiler that can take code from any frontend or language and translate it into Arc, a general-purpose, data-driven intermediate language. Code in Arc is universal and optimized on-spot with efficient code generation for the hardware you have available. Arcon’s runtime engine is scalable, streaming-first and is built entirely in Rust to guarantee memory safety, fault-tolerance and high performance for many types of analytics.
