Lunch Talk: Riccardo Tommasini “Stream Processing: From query languages to systems and back”

The BIFOLD Lunch Talk series gives BIFOLD members and external partners the opportunity to engage in dialogue about their research in Machine Learning and Big Data. Each Lunch Talk offers BIFOLD members, fellows and colleagues from other research institutes the chance to present their research and to network with each other.

The Lunch Talk takes place at the TU Berlin. For further information on the Lunch Talks and registration, contact Dr. Laura Wollenweber via email.

Data stream processing is more than two decades old but has only recently reached the plateau of productivity. This is due to three important things: the emergence of production-ready streaming systems, the democratisation of streaming pipelines via declarative access, and the growing need for real-time results. Recently, SP has left its analytics envelope and is heading towards more sophisticated applications, requiring more expressive languages, data models, and state management techniques. This is inevitably shaking its foundations.

The SP research cycle is heading again towards query language design after more than a decade of streaming system development. More specifically, SP is calling for language-system co-design!  In this talk, Riccardo Tommasini will give an overview of the recent and ongoing research work of his group on streaming languages, provenance for streams, and graph stream processing. Moreover, he will talk about the Polyflow library, which was designed after the lessons learned in these years and within the scope of his ANR project on “Multimodal and Polyglot stream processing”.

Bio: Riccardo Tommasini is a Maître de conférence (Associate Professor) at INSA Lyon, LIRIS Lab and a Visiting Professor at the University of Tartu, Estonia. Riccardo holds a Ph.D. Cum Laude from the Department of Electronics and Information of the Politecnico di Milano. His thesis, titled *Velocity on the Web*, investigates the velocity aspects that concern the Web environment. His research interests span Stream Processing, Knowledge Graphs, Database System, Logics and Reasoning, and Programming Languages. His Research has been recently funded by the French National Research Agency ANR.
