👉 At the #CDMS Workshop I will give a lightning talk on interoperability and composability in #federated #DataSystems, showing how XDB (our work from #ICDE2023) enables federated query processing and XDBC enables efficient cross-system #DataTransfer.

👉 At the #AIDB Workshop Bene will present our work on ADAPT, a data-driven optimizer that automatically tunes transfer parameters to changing environments. With Benedikt Didrich, Vasilis Gkolemis, @matthiasboehm7.bsky.social, and Volker Markl.

🚀What do data transfer and space missions have in common? A lot of parameters you need to tune in complex environments! 👉At #VLDB2025 we will showcase Enter the Warp, an interactive game that turns data transfer into a space mission using XDBC, our work presented at #SIGMOD2025

Work done in collaboration with Kaustubh Beedkar, @matthiasboehm7.bsky.social , and Volker Markl at @bifold.berlin and Technische Universität Berlin, and supported by @softwarecampus.bsky.social.

We argue that existing data transfer tools fall short in today's diverse environments. We introduce XDBC, a framework for fast and scalable data transfer across heterogeneous systems and infrastructures, whether you're working with #PostgreSQL, #Pandas, #ApacheSpark, or anything in between.

It was great to get feedback, connect with people from industry, and talk all things #PostgreSQL. #PGConf is such a vibrant community: Thanks to everyone for the engaging discussions!

🐘Really enjoyed presenting part of my PhD work (at @bifold.berlin/@tuberlin.bsky.social) on XDB for #decentralized query processing in #federated #databases at @pgconfde.bsky.social!

Parsing #Excel #spreadsheets at lightning speed — that’s exactly what we built SheetReader for!

Haralampos Gavriilidis @harrygav.bsky.social · 13/03/2025

Through my project #PolyDB, I had the chance to lead a team of amazing research assistants, travel to top conferences, and meet incredible people—experiences that wouldn’t have been possible without Software Campus.

Haralampos Gavriilidis @harrygav.bsky.social · 13/03/2025

Being part of Software Campus has been an incredible opportunity to bridge academia and industry, with great leadership trainings and 100k€ funding for research, travel, and equipment—I highly recommend applying if you're a PhD student in Germany! 🚀
