It is a common misconception that Parquet requires (slow) reparsing metadata and is limited to built in indexing structures. Using External Indexes, Metadata Stores, Catalogs and Caches to Accelerate Queries on Apache Parquet with ApacheDataFusion datafusion.apache.org/blog/2025/08/1…

CLOSET has been free for the past 5 years-thank you all for your support, especially the DB venues! To help cover hardware costs and a bit of my time, it is now transitioning to a paid service model. #SIGMOD #VLDB #EDBT #ICDE

🚀 Amazing community project! vLLM CLI — a command-line tool for serving LLMs with vLLM: ✅ Interactive menu-driven UI & scripting-friendly CLI ✅ Local + HuggingFace Hub model management ✅ Config profiles for perf/memory tuning ✅ Real-time server & GPU monitoring ✅ Error

Teaching in the age of AI has brought challenges I never expected—even leading my students and I back to paper exams. 📄✏️ Fortune just published a thoughtful piece on how we’re navigating the role of humans and machines in education, research, and beyond. You can read it here:

To solve any problem, you don't have to be super smart. You just have to 1) be able to break down problems into subproblems, 2) be slightly smarter than the hardest of the atomic subproblems. The real challenge is that the process can take a very long time.

Got some hot research cooking? 🔥 The SaTML Conference paper deadline is just 9 days away. We are looking forward to your work on security, privacy, and fairness in machine learning. 👉 satml.org/call-for-paper… ⏰ Sep 24

We're releasing the DASLab GGUF Quantization Toolkit! 🚀 First open-source toolkit bringing GPTQ + EvoPress to Georgi Gerganov's GGUF format, enabling heterogeneous quantization based on importance. Result: Better models at the same file size. [1/5]

Dear Database Researchers, We are now seeking nominations from the database community for the 2025 Research Highlights. Check the following msg for details: listserv.acm.org/SCRIPTS/WA-ACM…

Congratulations Stefan Grafberger on the successful PhD defense at UvA Amsterdam. 🎆 It was an extraordinary experience being on the committee and attending the event. All the best for the start at Snowflake.

A postcard from ADBIS/TPDL 2025 in Tampere, Finland last week. It was a great and really enjoyable event.

How does DeepSeek Sparse Attention (DSA) work? It has 2 components: the Lightning Indexer and Sparse Multi-Latent Attention (MLA). The indexer keeps a small key cache of 128 per token (vs. 512 for MLA). It scores incoming queries. The top-2048 tokens to pass to Sparse MLA.
