Paper: dl.acm.org/doi/10.1145/...
Podcast: disseminatepodcast.podcastpage.io/episode/hara...
Project website: www.polydbms.org

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.

🚀 📄 Paper and Podcast Drop! 🎙️
Our #SIGMOD2025 paper on #data #transfer was just published on ACM.
Bored to read? The podcast with Jack Waudby on The Disseminate podcast is out too.

The XDB research project is a collaboration with Leonhard Rose, Joel Ziegler, Jonathan Gerloff, Benedikt Didrich, Kaustubh Beedkar, and Volker Markl at @bifold.berlin & @tuberlin.bsky.social and supported by @softwarecampus.bsky.social!

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!

Thank you to Stefan Halfpap, Haralampos Gavriilidis, Lukas Pirch, and Stephanie Brandl for their excellent tutorials this afternoon at #BIFOLDDay2025.
We look forward to the Spring Reception starting at 4 PM!

DuckDB Extension: duckdb.org/community_ex...

Core Parser with links to R & Python bindings, and the PostgreSQL extension: github.com/polydbms/she...

Work done in collaboration with @elenitz.bsky.social and Volker Markl at the @tuberlin.bsky.social @bifold.berlin and supported by @softwarecampus.bsky.social

Kudos to Felix Henze for leading the core parser implementation, Jonas Benn for building the @duckdb.org extension, and Joel Ziegler for the #postgresql extension!

I recently joined Jack Waudby on the @disseminate as part of the "DuckDB in Research Podcast" series to talk about SheetReader and our DuckDB community extension.

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

A huge thank you to the Software Campus team Stefan Jazdzejewski, Susanne Kegler, Natalia Teixeira Silva, and Tiziana Maglia for making this program such a valuable experience and Holger Konle from DLR Projektträger for his invaluable support throughout the project!

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.

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! 🚀
