This Friday 16:00 CET Dutch Seminar on Data Systems Design I'm organising a panel discussion with Raul Castro Fernandez, Juan Sequeda, george fletcher, Yannis Velegrakis Tw, @MadelonHulsebos and Christos Koutras. Is dataset discovery automatable or should we focus on human-in-the-loop solutions? Is DB research on the right path?

Feb 14th is a proper day for reminding people of our Valentine project: Project page: delftdata.github.io/valentine/ Repo: github.com/delftdata/vale… Python package: pypi.org/project/valent… Help your data find their matches! #Python #databases TU Delft

We have extended our DEBS paper with: - discussing transactional #serverless functions and dataflow systems - a discussion on isolation levels - more experiments ... Here: doi.org/10.1016/j.is.2… With Martijn de Heus Kyriakos Psarakis Marios Fragkoulis

I'm thrilled to to announce that I was awarded the #VIDI grant from NWO Nieuws! The funding will allow me to build a transactional actor-like Cloud programming model on top of dataflow systems!

At around 17:30 Amsterdam time at CIDR 2025 I will be presenting how one can take an object-oriented Python programs and compile it to a dataflow graph and deploy it on streaming dataflow engines. (cidrdb.org/cidr2023/paper…). w Kyriakos Psarakis,Wouter Zorgdrager,Marios Fragkoulis, and Guido Salvaneschi.

The first step towards eliminating error-management code in stateful cloud applications was presented today CIDR 2025. More to come in the future!

Tomorrow from 17.30 (EEST) I will present and demo a 🇬🇷 greek themed 🇬🇷 scenario for Topio marketplace, and showcase the search and discovery components of the platform. If you are at edbticdt2023, drop by the demo session to meet and talk more.

We received 🥇best demo paper award 🥇 at edbticdt2023!

On Valentine’s day, all you need is pip 😍 Whether you found your match in life or not, Valentine matches your datasets. Feb. 14th anniversary-release (v0.2.0) includes: — faster batch-matching — more string similarity functions — redesigned metrics ++ github.com/delftdata/vale…

We managed to get the complete TU Delft “data” team in IEEE ICDE Conference in Utrecht, NL. Here is how it looks like (for now) :)

After some exciting and productive years at TU Delft and WIS Delft, last Monday I successfully defended my PhD dissertation on tabular schema matching! Always grateful to the people that co-advised me, and especially Asterios Katsifodimos!

We've been developing a runtime for Transactional Cloud Apps. Here is why we adopted (streaming) stateful dataflow graphs. "Transactional Cloud Applications Go with the (Data)Flow" K. Psarakis, G. Christodoulou, M. Fragkoulis, A. Katsifodimos. CIDR'25: kpsarakis.com/assets/pdf/sty…
