This is a demo of what a Blog / News Aggregator (Planet) for the Valkey Community / Ecosystem would look like.
(will be replaced by Planet Valkey)
(update your bookmarks, because soon, this website will stop working)
(the reason for replacement is that the initial URL is on the wrong domain, and new name and URL are better)
(before this website stops working, announcments will be made, and service will slowly degrade to nudge migration)
(announcments will include posts in the feed to reach people not checking the website)
(degradations will include removing subscriptions, and reducing refresh frequency)
(feel free to follow progress and share feedback in this GitHub Issue)

This release brings MySQL-style grants to more service user resources, and expands OpenTelemetry and Valkey configuration options.
Highlights for this release:
mysql_grants field for managing MySQL grants on the service user.Everything you need to monitor Valkey is already in the Prometheus ecosystem. This post is about how kube-prometheus, redis_exporter, and BetterDB Monitor come together to give you a complete picture of a running Valkey cluster, one tool per observability dimension.
Here's the one-minute version.
♦A Valkey cluster has two distinct observability dimensions: what's happening ins [...]
This release adds automated credential rotation, along with several smaller reliability and configuration improvements.
You no longer need to rotate service user passwords manually. With the new
ServiceUserRotation kind, you can manage a rotating pool of service users behind a stable connection Secret. Credentials can be rotated without disrupting dependent workloads.
We published five security advisories in Valkey's first 21 months, from the March 2024 fork through the end of 2025. We published seven advisories in the first eight months of 2026 and shipped almost three dozen security-adjacent fixes. In one two-week stretch, three researchers who did not know about each other reported the same bug: a use-after-free in the script debugger, an uncommonly used f [...]
The KV cache is huge, so shipping it over a network should be a non-starter. I benchmarked DRAM, local NVMe, and remote Valkey to find out what the hop really costs, and the answer wasn't what I expected.
[...]Nobody goes looking for a big key until something else breaks. One shard hits its memory limit while the others sit half idle, or p99 climbs with no change in traffic, and somewhere in the keyspace is a multi-megabyte hash nobody remembers creating. Valkey Admin 1.1 adds big key detection, which ranks the largest keys across every primary of a running cluster in one view, so you can find it with [...]
This release adds new configuration options across several services and promotes beta VPC peering resources to general availability.
Highlights for this release:
password_encryption_type field showing the hashing algorithm used for the stored password.Momento Cache puts high-performance Valkey at your fingertips. Cluster provides direct control over topology, while Flex automatically optimizes resources.
[...]Valkey 9.0 introduced Atomic Slot Migration (ASM), a new resharding mechanism that replaces the traditional key-by-key migration process with a replication-inspired approach. Instead of copying individual keys using MIGRATE, the source node establishes a dedicated connection to the target node and streams the contents of the migrating hash slots, followed by incremental updates unti

Fifty extra indexes don't slow down your writes, but one vector field slows them down 11x. I wanted to figure out why valkey-search behaves this way, and it wasn't what I expected.
[...]The role of databases has shifted significantly as modern applications must deliver real-time analytics, dashboards, and machine learning alongside low-latency transaction processing. Handling these diverse demands with a single relational database has become unsustainable under growing data volumes. Consequently, organizations are adopting specialized database architectures where multiple engin [...]
Benchmarking your Valkey deployment allows you to understand how your infrastructure behaves under load and where its limits are. And Valkey leverages this with an easy-to-use tool that allows you to get actionable figures for your deployment and to evaluate that performance.
This blog post explores the functions of the tool and some common traps you might encounter on your first run.
[...]A filter that looks like a query detail can change how Valkey searches your vectors. By the time you notice, the important decisions are already behind you.
[...]Valkey 9.1 introduces three optimizations that reduce the per-key memory overhead without requiring any new commands or configuration changes.
These reduce the memory required to store strings and sorted sets, up to 44% overhead for string keys and up to 8.5 bytes per sorted set member for typical short members. These savings add up quickly when millions of keys are in use.
This bl [...]
Amazon ElastiCache now supports Graviton4-based M8g, R8g, and C8gn node families for Valkey and Memcached. Graviton4-based nodes provide up to 47% higher throughput, up to 43% lower P99 latency, and up to 31% better price-performance for on-demand pricing over Graviton3-based nodes of equivalent sizes on Amazon ElastiCache for Valkey, depending on node family, size, and workload configuration.
Dumanshu Goyal discusses optimizing data layers for low-latency workloads like AI feature stores. Drawing lessons from NASA's Space Shuttle, he explains how proxy architectures introduce hidden CPU costs, elevated tail latencies, and blast-radius risks. He demonstrates how direct-access Valkey architectures achieve microsecond latency, improve resilience, and slash infrastructure costs.
By [...]ClusterControl 2.5.0 is here, and it marks a milestone for the platform: ClickHouse joins the family of supported database engines — and with it, a capability no analytics vendor’s cloud can offer you.

Modern AI inference stacks have split into layers, and each layer needs memory-speed access to something. Semantic caching needs vector similarity over recent prompts. Inference engines need a place to park KV tensors between requests. Retrieval-augmented generation (RAG) pipelines need filtered retrieval in a single round trip. The layer in front of all of it needs counters and rate limits that [...]
The community gathered at the Valkey Unlocked Conference to celebrate two years of innovation and ecosystem growth. In a keynote titled, "The Power of Community," Sailesh Krishnamurthy (VP of Engineering at Google) shared core insights on what it takes to build a thriving, resilient open source project and where the technology goes from here.

Across four releases, I/O-threading changes removed a serial copy bottleneck, cut p99 latency, and brought large GETs to line rate on our 200 Gbps test rig.
[...]If you’ve used Valkey for very long you’re probably aware of the different primary data types in the core: strings, hashes, lists, sets, sorted sets, and streams. Each data type has an accompanying set of commands that manipulate that data type. For example, you use HSET to set a field and value pair to a hash, but you don’t use, for example, HSET to add an element to a list. What i
