Planet for the Valkey Community

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.

Momento Cache puts high-performance Valkey at your fingertips. Cluster provides direct control over topology, while Flex automatically optimizes resources.

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 [...]

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.

AI agent memory turns a stateless large language model (LLM) into an assistant that knows its users and delivers personalized, relevant responses. Implementing an agent memory layer can cut token cost by up to 90% and keep responses under 2 seconds (Mem0 benchmarks). Without memory, responses lose relevance, users repeat themselves, and token costs climb as raw history accumulates.
