Turbopuffer (vector DB) architecture is a fairly interesting example of object-storage backed tiered DBs combined with data structure practices from DBs. turbopuffer.com/docs/archite... Here are the tradeoffs that makes it work: 567-labs.github.io/systematical...

As we test Kubernetes clusters beyond the supported 5,000+ nodes limit at LinkedIn, we're finding out 'List API' calls are a bottleneck in cluster reliability. So I'm publishing a deep dive about why this is a problem and what you can do about them. ahmet.im/blog/kuberne...

Open sourcing a new kubectl plugin called `kubectl node-resource` that queries allocations/utilizations for all/subset of the Kubernetes nodes. It has optimizations for large clusters. We've needed this in our set up to quickly answer questions. github.com/ahmetb/kubec...

Glad to have @madhavjivrajani.bsky.social join us at LinkedIn compute team this summer. I’m constantly impressed by the depth of his kube-apiserver expertise.

New article on my blog that explains all the various ways Kubernetes can evict your workloads. This wasn't all documented in one place so I'm hoping this helps the teams operating with Kubernetes in production. You'll also find a cheatsheet in the article. ahmet.im/blog/kuberne...

📝 Drafting an article about Kubernetes controller development mistakes and anti-patterns we see beginners make based on what we learned over the past couple of years. I hope to publish on Tuesday. Anything you wanna add?

TIL the Pacific salmon doesn’t have enough energy to swim back to the ocean after spawning. One of the local parks smells like rotten flesh. 🥴

Newest addition to my home office set up is the BenQ Halo light with both desk and back lighting. This will make the dark days of Seattle fall bearable.

It was great to catch up with many GCP & Azure friends at #KubeCon after so many years.

We've now published a blog about how LinkedIn runs large stateful apps with a generic operator on Kubernetes. www.linkedin.com/blog/enginee... Don’t forget to come to our #KubeCon session on Thursday.

I’ll be at #KubeCon after 5 years! Hoping to catch up with all the friends in the hallway track and the parties.

At LinkedIn, we run stateful systems on bare metal servers as a first class citizen on Kubernetes. That's why we built our own stateful workload operator. Join our #KubeCon talk to learn why StatefulSet didn't cut it for us and how we work with local storage. kccncna2024.sched.com/event/1i7n9/...

Over the weekend, added server-side table printing support to `kubectl pods-on` plugin. github.com/ahmetb/kubec... I did this because the table printed by "kubectl get pods" actually have a significant amount of server-side calculation that's not worth reimplementing on the client-side.
