Migrating from Redis to Valkey? Don't just swap the port. Avoid catastrophic data loss by auditing modules first.

Our SRE runbook for a zero-downtime migration on Ubuntu 24.04 is live.

The Blueprint:
✅ Pristine RDB module audits
✅ Deep TLS (v1.2/1.3) ciphers
✅ HAProxy traffic shifting
✅ Prometheus observability

Deploy on ServerMO Bare Metal for raw memory bandwidth and zero cloud jitter.

I’m currently in León, Spain, making my way up to Stockholm for DIS2026 to talk about #Valkey.

My travel is truly trains, planes and automobiles: Train to Oviedo, Bus from Oviedo to OVD airport (40km from the train station 😑), layover in Frankfurt, Train from ARN to city centre and finally an Uber to my hotel in northern Stockholm.

I am so excited to **not** be heading to Las Vegas today for #reInvent.

I have to admit it’s a bit strange to not go after going every year since 2017 (well, 2020 was virtual) but my upcoming travel schedule would have meant 3 weeks of solid travel and that’s… not humane.

If you are going, check out how #Valkey is buying out the Taco Bell Cantina on Tuesday for a giant party 😏

Great to see the Arkime open source project supporting the @OpenSearchProject as search backend, to make high-volume network traffic data searchable and actionable.
BTW, Arkime also supports the Valkey project. Two projects championed by AWS Open Source 👏👏

Ended up kicking Docker Hardened Images to the curb.

The good folks at #Docker decided to update their #Redis image to use a distro-less start (no shell, no other utilities) *without changing the image tag*.

So when I started up my #Mastodon server after an upgrade, my customization script wouldn’t run in the container and I had to scramble to find an alternative.

Basically, they broke the contract of immutable image version tags. Won’t trust them again, even if it did harden #security further.

So this server is back to a good ol’ upstream #PostgreSQL image on #AlpineLinux. And #Valkey on #Alpine, too, because Redis Ltd..’s software licensing shenanigans are sketchy.

I spent probably a weeks worth of hours learning more #kubernetes so I could save $60 a month.

I have a nice 3 node kube cluster with a 2 node #keepalived #haproxy TCP load balancer. All on #ARM VPS.

Haproxy ingress
#ExternalDNS operator
#CertManager
#RookCeph
#ArgoCD
#KeyCloak
#ValKey
#Mastodon
#CloudNativePG #Postgresql

The #MSTDNDK Mastodon instance just migrated away from Bitnami's #Redis helm chart and container images to #Valkey.

#Bitnami and Redis both seem to be exiting the open source community, which could prevent us from staying current, meaning always running the latest versions of the software components that make up this instance.

We understand the need to monetize software, but see that as an opportunity to add premium paid features, not take away existing ones from open source. Doing so will make your potential future customers look for other solutions. Looking at you, #MinIO, Redis and Bitnami.

Please report any issues you might experience as a result of the move to Valkey. So far it looks peachy.

FastAPI на AMD FX-8320: оптимизация P99 latency в условиях ограниченных ресурсов (HDD, DDR3)

В 2026 году асинхронный Python уже никого не удивляет. Мы привыкли к автоскейлингу в облаках, но что делать, если ваш бюджет на инфраструктуру равен нулю, а в распоряжении есть только «печка» из 2012 года? Рассказываю про личный опыт выжимания максимума из FastAPI на AMD FX-8320: от тюнинга ядра Linux и PostgreSQL до миграции на Ed25519 и использования Rust-сервера Granian.

Почему СУБД такие медленные

Недавно на Хабре публиковался перевод статьи «Просто выберите Postgres» ( оригинал , англ. яз) с аргументами, что Postgres — оптимальная БД для десктопных и мобильных приложений. Аналогичное мнение высказывают в других популярных статьях вроде «До свидания MongoDB, здравствуй PostgreSQL» . Главным недостатком SQLite называют то, что данные хранятся в одном файле, а MongoDB (а также DynamoDB и Cassandra) — низкую производительность: «Всё это связано с тем, что подобные базы данных, по сути, представляют собой огромную распределённую хеш-таблицу. Единственные операции, работающие без необходимости сканирования всей базы данных — это поиск по секционному ключу и сканы, при которых используется ключ сортировки. …Если паттерны доступа существенно изменятся, то может потребоваться полная повторная обработка всех данных». Более производительные резидентные БД хранят данные в памяти (Redis, Valkey), но их использование ограничено объёмом ОЗУ. После такого заявления интересно посмотреть на независимые тесты производительности разных СУБД.

A couple of years back, a bunch of projects started switching to proprietary Source Available licenses like #SSPL. I predicted that they would soon regret it, as they started to be replaced with forks of their own software. Feeling pretty smug reading this ...

"Redis bets big on an open source return

The company is hopeful that changing its license will allow it to better compete with the Valkey fork."

@linux_mclinuxface A followup. For very large, complex input, the streaming solution is vastly more efficient.

The following expression generates a 4-dimensional array of dimensions 100×100×100×10, i.e. 10 million elements. Each element is a nested array containing 4 integers: the coordinates to that cell.

Due to inefficiencies in the current alpha version of the serialisation format, this array serialises to a 124 MB data stream.

The valkey:setobj function writes this array in serialised form to valkey. We can see that the entire operation takes 0.603 seconds (note that the actual numbers varies quite a bit, but this is a close enough average).

    time:runtime { c valkey:setobj "largeobj2" ⍮ ⍳100 100 100 10 }
Total time: 0.603

Now, let's do the same, but explicitly encode the array to a byte array and store it using valkey:set. This is pretty much identical to what happened before the blocked streaming was implemented:

    time:runtime { c valkey:set "largeobj2" ⍮ encoder:encode ⍳100 100 100 10 }
Total time: 0.659

So in general, the streaming solution tends to be faster. That said, if I take the absolute best times I got for both, they were remarkably close (within 1 or 2 ms of 0.534, if I remember correctly)

Хроники Valkey: сайдкары, операторы и один очень упрямый кластер

Привет! Меня зовут Никита Кречетов, я работаю в команде Datawave в юните DBA в Авито . В этой статье рассказываю, как мы перевели полторы тысячи инстансов Redis на Valkey Cluster, как отказались от ручного решардирования и что это дало разработчикам и бизнесу. Материал будет полезен инженерам, которые ищут практичный опыт миграции на новые базы данных.

While you're considering switching to a redis fork, the one you want is redict, not valkey.

https://redict.io/

Both were forked from the same redis version. Why prefer redict? It's LGPL, and thus immune to further license shenanigans from any corporate stakeholders and embrace/extend/extinguish tactics from tech monopoly behemoths.

Valkey, being merely open source, is just as vulnerable as redis itself was.

#redis #redict #valkey #LGPL #OpenSource #copyleft

@rnanclares I can also take a true #opensource fork like #redict or #valkey
I am rather interested in just using the software directly as WMS cache without any other tool in combination

Как компании зарабатывают на опенсорсе, а потом выкидывают его

Финансирование разработки Kubernetes крупнейшими спонсорами на GitHub за последние десять лет, источник Эти компании сначала при помощи сообщества разрабатывают опенсорсный софт или берут готовый, строят на нём прибыльный бизнес, зарабатывают миллионы. А потом меняют лицензию, оставляя контрибуторов, пользователей и партнёров в недоумении, что им делать. Такова бизнес-модель некоторых современных компаний вроде Redis Labs . Но ещё хуже поступают крупные облачные провайдеры. Они просто используют готовые решения, вообще не занимаясь разработкой и убивая бизнес «паразитов», описанных выше. Здесь вообще паразиты в квадрате. И весь этот террариум кормится опенсорсом.

Redict 7.3 Released As Fork Of Open-Source Redis

#fork #foss #redict #redis #valkey

https://www.phoronix.com/news/Redict-7.3-Redis-Fork?utm_medium=erik.in&utm_source=mastodon

Forking is easy, ideas are cheap — but this blog post/announcement by #Redis successor (more correctly: one of multiple free software Redis successors) #Redict sounds really reasonable: https://redict.io/posts/2024-04-03-redict-7.3.0-released/

Focus on stability over new features (the production projects we use(d) Redis in required mostly 2015-era features; I bet that’s true for many users) to distinguish itself from and peacefully coexist and complement with other forks like #Valkey 👍

I'm not really sure it's a good thing the #LinuxFoundation has now also forked #Redis: Their fork #Valkey is announced to be backed by major large companies like AWS, Google, Ericsson, Oracle (duh!), but of course keeps using a BSD license.
https://www.linuxfoundation.org/press/linux-foundation-launches-open-source-valkey-community

This might make it a lot harder for the #Redict, that changed to LGPL, to keep traction. But copyleft licenses are a necessary against projects going proprietary again just like Redis did.

That moment when you get quoted on LWN...

[Перевод] Масштабирование кластера Valkey до 1 миллиарда запросов в секунду

Предстоящий релиз Valkey 9.0 несёт в себе значительные улучшения в отказоустойчивости больших кластеров, позволяя масштабироваться до 2000 узлов и достигать производительности свыше 1 миллиарда запросов в секунду, и всё это с гарантированно ограниченным временем восстановления. В этой статье мы рассмотрим, как работает система кластеризации Valkey, а также архитектурные усовершенствования и тщательное тестирование, которые сделали возможным такой уровень масштабирования.

Eventually tagging cache will have to come back to #Laravel sooner or later.

What about trying to re-implement it in time for Laravel 13? That would mean to depend on Symfony Cache.

My only warning is that #Valkey and #Memcached are vastly superior in performance, but on controlled scenarios, this is imperceptible. Plus, #Meilisearch and #TypeSense are vastly superior.

The #Blender situation is fascinating. Bradley highlights an important aspect of what's going on.

I think there is wide misunderstanding in how money has influence over #openSource projects. Make no mistake, given the source of the money here, people are rightfully concerned.

However, there is typically (but not always) good firewalls between money and governance (i.e. engineering).

It's possible to not take money at all (see #Valkey) but it's not easy to get lots of things done.

I am happy to announce our new docs for #valkey based rate limits, so you can replace #redis.
It's faster in in tail latency percentiles like p999.

I've just released PubSub Chat, a "toy" chat system that only relies on Redis-compatible / PubSub-enabled database (and no other server app)

https://codeberg.org/brunobord/pubsub-chat

I've tried to document it the best I could ; don't forget that it's quite unsafe and is NOT meant to replace IRC, Matrix, XMPP, etc.
But that was fun reviving it.

So, decided to get them rookie `/queue` numbers up so did a quick bit of caching. For a 12-job queue, I went from 240 RPS (Python/Flask) to 680 (Golang/Gin) then to 3400 RPS with some proper caching. The `/workers` endpoint would benefit as well, but I think its performant enough though I may end up adding a bit of caching later.

I've been using Valkey (and Redis before it) for years when building scripts or small apps to store a bit of data.

Even though I'm not storing a lot of data, it has always irked me that it needs to be in memory all the time.

Last night I found kvrocks, an Apache project, which provides a redis interface, but stores data on disk in rocksdb. Even better, it has "namespaces", so I can separate each app easily by credential.

This day just keeps on giving, now was a #ValKey container in my #synology 😅

#ValKey is just amazing, the capacity of this thing is huge and improves alot the applications.

This was the former #Redis, that still exists but this is a fork.

Woohoo! Another bit merged into #Valkey .

Timeline: I got super annoyed at something on Friday after lunch. A little needless barrier carried forward for years.

I thought about writing an issue but I looked at the code and thought "I can fix this."

First PR took about 30 mins, got feedback in an hour. Made the changes based on the feedback (~+20 minutes, once I got my bearings).

Then 6 reviews over the weekend and it was merged by 10am on Monday. Valkey 9.1 bound!
