Planet for the Valkey Community

Valkey rarely runs on its own. It often sits in front of a database, and when a page gets slow the answer is either a cache that is not being hit or a query that got worse. Checking both usually means one terminal on valkey-cli and another on the database, and holding the two halves of the picture in your head.

That is the situation I want to walk through, using a graphical u [...]

• Aiven for Kafka, MySQL, OpenSearch, PostgreSQL, and Valkey user resources and data sources now expose a mysql_grants field for managing MySQL grants on the service user.
• New OpenTelemetry integrat [...]

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:

• Aiven for Kafka, MySQL, OpenSearch, PostgreSQL, and Valkey user resources now expose a password_encryption_type field showing the hashing algorithm used for the stored password.
• Aiven for Kafka [...]

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.

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. Wherever you run ClusterControl — on-premises, in any cloud, or hybrid — you can now deploy ClickHouse either as a standalone OLAP […]

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.

With Harbor v2.15.2, the Harbor team replaced Redis with Valkey as its internal cache backend. This was a deliberate open source choice that highlights the flexibility and resilience of the open source ecosystem.

Harbor is a CNCF graduated open source container registry, a place where organizations can store, manage, and secure container images, Helm charts, OCI artifacts, CNAB (Cloud Nat [...]

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 [...]

DoorDash has developed Entity Cache, a transparent proxy caching platform built on Envoy and Valkey to reduce redundant service-to-service requests across its microservices architecture. Operating within DoorDash’s service mesh, the platform serves over 1.5M requests per second with 99.99999% availability through caching, event-driven invalidation, failure handling, and performance optimization [...]

KV cache starts out as an implementation detail of inference. As inference systems evolve, it is becoming a first-class systems primitive.

AWS has recently introduced durability for Amazon ElastiCache for Valkey, enabling reliable data retention across failures and expanding support beyond caching to persistent workloads. The feature offers new options that prioritize either minimizing data loss or maintaining lower write latency, expanding the range of use cases supported by the Redis fork.

The best systems are often the boring ones. Boring because they continue working predictably when traffic spikes, dependencies drift, workloads evolve, or failures start cascading across systems at 3AM.

That idea was constant at Unlocked Conference in Seattle.

More than 140 engineers representing over 50 companies gathered at T-Mobile Park for a full day of 20 technical ta [...]

The alerts are firing. Users cannot complete requests. The cache dashboard shows CPU normal, memory normal, hit rate normal, p99 within SLA. The Valkey node metrics are all green. The cluster topology has not changed. Yet the application is still failing.

This is one of the more disorienting situations in distributed systems. The component everyone assumes is the culprit is behaving perfe [...]
