Today is the new semester for @CMUDB's Intro to Database Systems! We're going harder into material than ever before. Projects are more challenging but you can use LLMs to help. We also have 10min talks each Wed from leading DB companies. Follow on YouTube:

🔔VLDB 2025 Keynote Preview: Join Stratos Idreos from @HarvardDASlab as he reimagines systems design in the AI era with his keynote on "Alphabets, Grammars, Calculators & the End of Hand-Crafted Systems". More details: https://t.co/0cCh8E3rIF #VLDB2025 #DataSystems #AI

Congratulations, Papon, for successfully defending your PhD thesis!! Looking forward to seeing what you will be doing next!

📢📢VLDB 2026 will have a ShadowPC! Apply at https://t.co/rhCD6pwIWk by March 1! Great opportunity for folk who are new to the data management community and want to gain experience with paper reviewing. For more info, see the application form. Chairs: @zistvan, @wangtzh , & I.

#NEDB2025 deadline extended to Dec 18th! Submit your posters and talks https://t.co/aM1N0t1kbx More info: https://t.co/rODqRAgrtM Three exciting #keynotes by: Mike Stonebaker, MIT Dhruba Borthakur, OpenAI Jake Luciani, DataStax https://t.co/2ytZ1fGVy0

Kudos to all amazing collaborators and studens in these projects!

(3) We design a variation of the round-robin file-picking policy that is very close to the optimal compaction, both in terms of performance stability and write amplification (to appear at EDBT). Pre-print:

(2) We also developed Concurrent Updatable Bitmap Indexing (or CUBIT) that uses lock-free fine-granular out-of-place updates to offer superb performance and scalability (to appear at VLDB). Pre-print:

(1) We developed a new sortedness-aware index with a simple yet very powerful design called Quick Insertion Tree (QuIT), which allows near-bulk-load performance for near-sorted data without any performance hit on queries (to appear at EDBT)! Pre-print:

Excited to share that we got three papers recently accepted that focus on delivering better indexing! A thread:

Last week, at #SIGMOD2024, @BU_DiSClab gave five talks: 2 research papers in the main conference, 2 #DBTest workshop papers, and one invited talk in the 20th instance of #DAMON. I am also very thankful to receive the ACM SIGMOD Distinguished PC Member award for the third time.
