Avid hiker, maintainer of the Valkey project, and engineer at AWS. Thoughts are my own.
Last Friday, #Valkey released fixes for 7.2, 8.0, and 8.1 to address some Lua vulnerabilities that may allow RCE from an authenticated user. It's a good time to remind folks to always lock down your Valkey instances, even in secure environments. See github.com/valkey-io/va... for all the details)

So the #Valkey project is working on a packaged version of Valkey along with popular extensions (like LDAP authentication and vector similarity search). The plan is to call it `valkey-extensions`, but that the name might imply it's just extensions and not the core. Folks have better ideas/thoughts?

It's a bit last minute, but if anyone is interested in a live stream about tuning Valkey to run efficiently on multiple cores, we'll be hosting it in a couple of hours www.linkedin.com/events/73360.... There will be a recording as well.

Redis relicensed (under AGPL, which many cannot use). Valkey project, a Redis fork and still under an #opensource BSD license, continues to thrive in adoption and community at @linuxfoundation.org. Read more about what's next for Valkey:

Just read a great blog by a friend about how to properly measure the performance of Valkey and Redis. When evaluating high performance systems, there are a lot of parameters which can affect the total throughput and it's easy to come up with "synthetic numbers". www.gomomento.com/blog/valkey-...

What if we could pick up a k8s cluster and move it w/out service disruption?

We demo’d this at Kubecon NA 2024 by moving a @kubernetes.io cluster running Valkey from AWS to Azure and then GCP all without disruption! this is pure magic from @felicitas.pojtinger.com .

It’s @reconditerose.bsky.social quoting antirez at #MonkiGras on the importance of optimising for joy!

"[..] We believe writing code is a lot of hard work, and the only way it can be worth is by enjoying it. When there is no longer joy in writing code, the best thing to do is stop. [..]”

We just launched a new release candidate for Valkey (the OSS fork of Redis). The main change is that we rebuilt the key/value store from scratch to take better advantage of modern hardware based on the work done at Google.

People keep telling me that Valkey should deprecate 32bit, but then we wouldn't have this delightful version of Valkey that runs entirely in your browser with a CLI! zarkash-aws.github.io/try-valkey.g...

It's the 32bit version of valkey running ontop of the v86 emulator. More features coming soon!

The Valkey community is hard at work developing a high performance vector similarity search implementation, and we're looking for folks interested in providing high level API and directional feedback here: github.com/valkey-io/va.... They'll be a more concrete implementation soon once we're aligned.
