@PostgreSQL has long powered core @OpenAI products like ChatGPT and the API. Over the past year, our production load grew 10× and keeps rising. Today we run a single primary with nearly 50 read replicas in production, delivering low double-digit millisecond p99 client-side latency and five-nines availability. In our latest OpenAI Engineering blog, we unpack the optimizations we made to to scale @Azure PostgreSQL to millions of queries per second for more than 800M ChatGPT users.

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…

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. ottertune.com/index.html

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…

Everyone loves @PostgreSQL these days. But there is a part of Postgres' architecture from the 1980s that causes many performance + storage issues for people. So @BohanZhangOT and I wrote a new @OtterTuneAI blog article about why it is and why it sucks: ottertune.com/blog/the-part-…
