nice to see some @PrometheusIO community folks starting discussions about porting some things to #rustlang github.com/bwplotka/prombenc…

look forward to seeing everyone in Barcelona next year! registration is open, book hotels early as the event is on track to be our largest yet!
That's a wrap on #KubeCon NA 2026! Thank you to all maintainers, contributors, speakers, and attendees for such a fantastic event. We look forward to seeing everyone at KubeCon EU (March 15-18, 2027, Barcelona, Spain) as well as online and other yet-to-be-announced events!

Live at KubeCon + CloudNativeCon North America: Congratulations to our 2026 Lifetime Achievement Award winners, Julius Volz and Rita Zhang (@ritazzhang)!
Thank you for spending over a decade building the core observability and security foundations that our community relies on every day.

Behind every release and milestone are the people showing up every day to build, maintain, and document open source infrastructure.
At KubeCon + CloudNativeCon North America, we recognized 11 contributors across our 2026 CNCF Community Awards.

This is huge. Probably the biggest realization for open-source @CloudNativeFdn metrics this year.
🔥 Scraping 345,000 active @PrometheusIO series every 15s and sending via Remote Write 2 or @opentelemetry OTLP takes on modern @golang collectors:
• ~1 GiB of RAM (WSS) with ups & downs (WAL compaction, cardinality bumps)
🚀 With @rustlang and @ApacheArrow via @opentelemetry otel-arrow using our new Prometheus scrape.rs crates:
• ~30 MiB of RAM (WSS, 5 MiB live heap)
• 2.6x–7.3x less CPU, flat for 23 hours 😱
I couldn't believe it. How is this even physically possible?
We have an opportunity to save $2.5B–$4B/yr in collector compute globally, and easily $100M+/yr at single-hyperscaler scale. We can scale 30x per pod, get hardware back, and deprioritize complex scalability band-aids like DaemonSet VPA and sharding.
Yes, I wrote the @OReillyMedia "Efficient Go" book, but for the last 2 weeks I've been becoming a Rust and columnar developer. There is no other way. This is the way.
And yes, we are starting a Prometheus.rs (ecosystem-wide) SIG — see #prometheus-rs-sig on CNCF Slack!
Huge thanks to the OpenTelemetry otel-arrow community for doing most of the work, Laurent Quérel for consulting, and the @ThanosMetrics & @PrometheusIO communities for columnar inspirations 💪
(Disclaimer: early numbers without full parity yet—with staleness, relabeling, and K8s discovery, compute needs will grow. Still, starting at 30 MiB WSS gives us tons of room!)

Live at KubeCon + CloudNativeCon North America: Congratulations to our 2026 Top Committer Award winner, Antonio Ojea (@Itsuugo).
His sustained technical leadership across Kubernetes networking, KIND testing, IPv6 dual-stack support, and DRANET continues to move our ecosystem forward.

The live Project Pavilion Map lets you select a kiosk and see a summary of the project, along with a direct link to its repository.
So while you’re exploring projects and talking with maintainers at KubeCon + CloudNativeCon North America 2026, you can also go directly from the pavilion to the code and learn more about what is being built.

#Kubernetes contributor meet & greet happening right now during lunch. we're talking origins of K8s and how to get started. near room 257 #kubecon with @kaslinfields @moficodes
FYI we launched a new site for CNCF Reference Architectures that showcase how companies are actually stitching together CNCF projects in production in a variety of different use cases #kubecon #cloudnativecon endusers.cncf.io/architectur…

Such an amazing journey! @nats_io just turned 16 as well.
A huge thanks to everyone in the ecosystem for your support.
It feels like we are just getting started. At @synadia we have never seen so much interest in NATS as the central nervous system to drive modern distributed systems, cloud to edge, and of course Agentic AI.
NATS has officially graduated from CNCF.
The open source messaging and streaming fabric now provides a proven communication layer for more than 2,000 organizations running distributed systems and agentic workloads.
