Talk at @microsoft on reinforcement learning for in-query optimization (SkinnerDB) is now online: youtu.be/Qy-JdTYe1u8 Thanks for the invitation! #Microsoft #SQLServer #ReinforcementLearning #SQL #data #databases #BigData #queryoptimization #MachineLearning

Nerd joke :-)

The birth of AI, 70 years ago!

My paper on DB-BERT, the database tuning tool that "reads" the manual, was accepted @2022Sigmod! Ideas: - Mine tuning hints from text via NLP - Refine mined hints based on trial runs - Select runs via reinforcement learning Code: itrummer.github.io/dbbert #ML #DB #NLP #SIGMOD2022

Join us for the Cornell University #Database seminar! Time: Mondays, 1-2 PM EST Details: tinyurl.com/ezf4jac2 Zoom: tinyurl.com/2p8uv2j8 Schedule below. #Databases #SQL #DataScience #ML #BigData #Retweet

Time for my annual rant on data science systems. 😈 <rant> A data lakehouse is a DBMS. A DataFrame system is a DBMS. An ML platform is a DBMS. A model store is a DBMS. A feature store is a DBMS. Those who fail to learn (+ves & -ves) from history are doomed to repeat it. </rant>

Happy Valentine’s day to those estranged database columns that could consider a join or union!

Many congrats to Victor Giannakouris, the newest member of my group, for an accepted paper on learned query optimizers at the #VLDB2022 PhD workshop! And that, btw., means we'll be giving five talks total at #VLDB2022! #AI #ML #QueryOptimization #PostgreSQL #MySQL #Spark Cornell Bowers Computing and Information Science

Happy 99th birthday to Edward Codd. "After a brief stint at Macy's men sportwear department, Codd joined IBM as a programming mathematician". I wonder what databases (and men's sportswear) would look like today if he had remained in fashion 😅 cockroachlabs.com/blog/codd-trib…

Having a paper accepted at VLDB 2025 🇬🇧 (#VLDB2022) which I am supposed to present, I might miss the conference due to my eVisitor 651 delay, while the conference date is quickly approaching. Any suggestions Department of Foreign Affairs and Trade 🇦🇺 Australian Government ?"

Congratulations to the authors of the demonstration paper "Share the Tensor Tea: How Databases can Leverage the Machine Learning Ecosystem" for winning the "Best Demonstration Award"! vldb.org/2022/?conferen… #VLDB2022 #BestDemo #Awards

🎉🎉🎉 Incredibly happy to announce that my CAREER Award "Mining Hints from Text Documents to Guide Automated Database Performance Tuning" has just been accepted by U.S. National Science Foundation! So grateful to everyone, students and colleagues, who made this possible! #LanguageModels #Databases #NLP

Really thrilled to be working with sainyam galhotra! Welcome to Cornell University, Sainyam!

🎉Many congrats to Victor Giannakouris for his accepted #SIGMOD2024 demo on λ-Tune! λ-Tune uses #LargeLanguageModels to support various #DB tuning decisions like - index selection, - query optimization, - parameter tuning. #GPT4 #LLM #SQL #Database #NLP #AI #ML #DBMS

🎉🎉🎉Many congrats to my student (soon-to-be) "Dr." Ziyun Wei for a fantastic PhD defense!! (thesis title: "Robust Querying for Data Analysis and Processing") Really proud & all the best for the next stage, Ziyun! #PhDDefense #PhD #QueryOptimization #RobustProcessing #Database
