Skyhook: Towards an Arrow-Native Storage System
Jayjeet Chakraborty, Ivo Jimenez, Sebastiaan Alvarez Rodriguez +3
With the ever-increasing dataset sizes, several file formats such as Parquet, ORC, and Avro have been developed to store data efficiently, save the network, and interconnect bandwi…
Tiny Autoscalers for Tiny Workloads: Dynamic CPU Allocation for Serverless Functions
Yuxuan Zhao, Alexandru Uta
In serverless computing, applications are executed under lightweight virtualization and isolation environments, such as containers or micro virtual machines. Typically, their memor…
In-Memory Indexed Caching for Distributed Data Processing
Alexandru Uta, Bogdan Ghit, Ankur Dave +2
Powerful abstractions such as dataframes are only as efficient as their underlying runtime system. The de-facto distributed data processing framework, Apache Spark, is poorly suite…
A Holistic Analysis of Datacenter Operations: Resource Usage, Energy, and Workload Characterization -- Extended Technical Report
Laurens Versluis, Mehmet Cetin, Caspar Greeven +5
Improving datacenter operations is vital for the digital society. We posit that doing so requires our community to shift, from operational aspects taken in isolation to holistic an…
Zero-Cost, Arrow-Enabled Data Interface for Apache Spark
Sebastiaan Alvarez Rodriguez, Jayjeet Chakraborty, Aaron Chu +4
Distributed data processing ecosystems are widespread and their components are highly specialized, such that efficient interoperability is urgent. Recently, Apache Arrow was chosen…

The Future is Big Graphs! A Community View on Graph Processing Systems
Sherif Sakr, Angela Bonifati, Hannes Voigt +38
Graphs are by nature unifying abstractions that can leverage interconnectedness to represent, explore, predict, and explain real- and digital-world phenomena. Although real users a…
The LDBC Graphalytics Benchmark
Alexandru Iosup, Ahmed Musaafir, Alexandru Uta +15
In this document, we describe LDBC Graphalytics, an industrial-grade benchmark for graph analysis platforms. The main goal of Graphalytics is to enable the fair and objective compa…
Massivizing Computer Systems: a Vision to Understand, Design, and Engineer Computer Ecosystems through and beyond Modern Distributed Systems
Alexandru Iosup, Alexandru Uta, Laurens Versluis +6
Our society is digital: industry, science, governance, and individuals depend, often transparently, on the inter-operation of large numbers of distributed computer systems. Althoug…
