Thanks for this hot take dude who doesn't know the 60 year history of databases. H/T @prempv Mike and I have a WIP paper that analyzes all the (failed) attempts to replace SQL + relational model. This tweet has motivated me to finish it and submit it.

SQL is going to die at the hands of an AI. I’m serious. @mayowaoshin is already doing this. Takes your company’s data and ingests it into ChatGPT. Then, you can create a chatbot for the data and just ask it questions using natural language. This video demoes the output. 🤯

In today's episode of why I love the internet, people in Iran are discussing whether I live with my mother and work on databases.

Somebody tipped me off that a 2022 paper out of Saudia Arabia blatantly stole our entire 2019 ICDE Bulletin survey paper on using ML automatically optimize databases. + 2022 Plagiarism: eajournals.org/ejcsit/vol10-i… + 2019 Original: db.cs.cmu.edu/papers/2019/pa…

It took three years to finish, but our follow-up to the 2006 "What Goes Around Comes Around" is finally out! Stonebraker and I examine the last 20 years in databases and discuss why relational databases + SQL will continue to remain on top. 📄PDF: db.cs.cmu.edu/papers/2024/wh…

Columnar file formats like Parquet/ORC are ubiquitous. Our VLDB paper with @XinyuZeng218 + @huanchenzhang + @wesmckinn studies their internals. TLDR: They're not optimized for modern hardware. Something new is needed. Paper: vldb.org/pvldb/vol17/p1… Code: github.com/XinyuZeng/Eval…

I'm to sad to announce that @OtterTuneAI is officially dead. Our service is shutdown and we let everyone go today (1mo notice). I can't got into details of what happened but we got screwed over by a PE Postgres company on an acquisition offer.

This is Thomas Neumann: db.in.tum.de/~neumann/index… People outside of academia may not know but he is probably the #1 DB systems researcher in the world. He sold his last DBMS (HyPer) to Tableau: hyper-db.de He just announced his new DBMS Umbra: umbra-db.com
