At long last, @chris.blue and I have submitted the final manuscript of Designing Data-Intensive Applications, second edition, to the publisher. There is always more that could be improved but at some point we just have to call it done. Now it goes into production; probably shipping in ~4 months.

I can’t help it but completely stop taking anything the person wrote seriously if it feels like they used an LLM in an email. I can understand if one would check tone or spellcheck, but I feel like writing should still be done by a human. Am I old fashioned here?

After twitter turned into whatever it has turned into I kept hoping for a while that it’ll somehow recover, and posting both there and on BlueSky felt cumbersome. I don’t have twitter on my phone anymore, so let’s see if BlueSky can be as good as old twitter.

Reading Sunk Works after reading the Qualcomm Equation, and can’t help but wonder what happened to engineering. I can think of 2 companies in the entire industry (which will remain unnamed) that are delivering projects of immense complexity with tiny resources, while others are lost in processes.

Folks on database internals discord are voting for the next book. It’s a perfect time to join. This will be the third book we will be reading together, after Transaction Processing, and DDIA. discord.gg/GmchY45BbS

This bears out in practice, yep.
But it may be more attributable to compaction strategies that limit the number of SSTables that may contain a key (e.g. leveled) and keeping up with compaction backlog.
Most Cassandra deployments using LCS and default blooms maintain an SSTable-per-read count of 1.

It's never too late to organize your huge pile of papers.
Found 549 papers, only 156 of which had highlights or notes. However about 350 were pre-processed/marked. I kept better notes.
Anyone got ideas about how to attach notes to PDFs?

Hello 🦋
Happy to see many familiar faces around. Wasn't easy to find all of you (I probably missed many), so I created a starter pack to make it easier to (re)connect and nerd out about distributed systems, programming languages, and container stuff. Let me know who I missed!
