CheckMate: Evaluating Checkpointing Protocols for Streaming Dataflows
George Siachamis, Kyriakos Psarakis, Marios Fragkoulis +3
Stream processing in the last decade has seen broad adoption in both commercial and research settings. One key element for this success is the ability of modern stream processors t…
Improving Sequential Recommendations with LLMs
Artun Boz, Wouter Zorgdrager, Zoe Kotti +5
The sequential recommendation problem has attracted considerable research attention in the past few years, leading to the rise of numerous recommendation models. In this work, we e…
Styx: Transactional Stateful Functions on Streaming Dataflows
Kyriakos Psarakis, George Christodoulou, George Siachamis +2
Developing stateful cloud applications, such as low-latency workflows and microservices with strict consistency requirements, remains arduous for programmers. The Stateful Function…
Leveraging Large Language Models for Sequential Recommendation
Jesse Harte, Wouter Zorgdrager, Panos Louridas +3
Sequential recommendation problems have received increasing attention in research during the past few years, leading to the inception of a large variety of algorithmic approaches.…
SiMa: Effective and Efficient Matching Across Data Silos Using Graph Neural Networks
Christos Koutras, Rihan Hai, Kyriakos Psarakis +2
How can we leverage existing column relationships within silos, to predict similar ones across silos? Can we do this efficiently and effectively? Existing matching approaches do no…
Stateful Entities: Object-oriented Cloud Applications as Distributed Dataflows
Kyriakos Psarakis, Wouter Zorgdrager, Marios Fragkoulis +2
Although the cloud has reached a state of robustness, the burden of using its resources falls on the shoulders of programmers who struggle to keep up with ever-growing cloud infras…
Hazelcast Jet: Low-latency Stream Processing at the 99.99th Percentile
Can Gencer, Marko Topolnik, Viliam Ďurina +11
Jet is an open-source, high-performance, distributed stream processor built at Hazelcast during the last five years. Jet was engineered with millisecond latency on the 99.99th perc…
Valentine: Evaluating Matching Techniques for Dataset Discovery
Christos Koutras, George Siachamis, Andra Ionescu +6
Data scientists today search large data lakes to discover and integrate datasets. In order to bring together disparate data sources, dataset discovery methods rely on some form of…
A Survey on the Evolution of Stream Processing Systems
Marios Fragkoulis, Paris Carbone, Vasiliki Kalavri +1
Stream processing has been an active research field for more than 20 years, but it is now witnessing its prime time due to recent successful efforts by the research community and n…
