The 2nd edition of Designing Data-Intensive Applications, by @martinkl and me, is finished and sent to the printers! Ebooks available next week, and print books in 3–4 weeks. Sigh of relief. 😅 (BTW, this is a good opportunity to support your favourite local bookshop!)

Today's Postgres vs. World Seminar Speaker: @MarcJBrooker will present the architecture of Amazon's Aurora DSQL (Postgres-compatible serverless OLTP DBMS). Zoom talk open to public at 4:30pm ET. YouTube video available after: db.cs.cmu.edu/events/pg-vs-w…

Here is my latest article on the world of databases: cs.cmu.edu/~pavlo/blog/20… All the hot topics from the last year: • More Postgres action! • MCP for everyone! • MongoDB gets litigious with FerretDB! • File formats! • Market movements! • The richest person in the world!

6 levels of OLTP database query latency: Nice: < 1ms Acceptable: 1-3ms Probably fine: 3-9ms Slow: 10-20ms Concerningly slow: 20-100ms Fix it now: 100ms+

Do you like databases? Do you want to hear two database professors rant about them? Do you need one of those professors to have a Turing Award for databases? If yes, then join Mike Stonebraker and I next Wed Dec 10 @ 1:00pm EST for database hot takes: dbos.dev/webcast-2025-i…

Wayne Rooney has revealed that he’d have chosen Ireland and that he was very close! 🤯 Rooney spoke with Carsley + McCarthy and he was called into the U21s Turning down the 21s, he admitted he likely would have accepted a Senior Call-Up! 👀

Microsoft Azure has over 40 data centers globally. Here, I visualize (most of) them on the globe along with inter-data-center latency.

Another great post + tool from Ben. Fun to see visualized and good breakdown of the tradeoffs of different sharding strategies 💯👏

It's finally here! Amazon Aurora DSQL might just be the future of distributed SQL databases. #serverless 🙌🚀

Finally!!! 🙌 #serverless aws.amazon.com/about-aws/what…

really looking forward to this @TG4TV expose of the Irish concrete disaster, fair play to them for going over to @Empa_CH to speak with Dr Andreas Leemann for the program to learn about what is causing family homes in Donegal to fall apart. Do tune in Wednesday 9.30pm💪
