This is a demo of what a Blog Aggregator for the Valkey Community / Ecosystem would look like.
Redis recently released a security advisory regarding CVE-2025-49844. This critical (CVSS 10.0) use-after-free (UAF) vulnerability in Lua scripting could allow authenticated attackers to execute remote code on older versions of Redis and Valkey with Lua scripting enabled. Developers are urged to upgrade to patched releases as soon as possible.

[...]Managing the topology of a distributed database is one of the most critical and challenging tasks for any operator. For a high-performance system like Valkey, moving data slots between nodes —a process known as resharding— needs to be fast, reliable, and easy.
Clustered Valkey has historically supported resharding through a process known as slot migration, where one or more of the 16,384 [...]
The Valkey open source data store has officially released version 9.0, marking its most significant update since the project’s launch

[...]For Valkey's second major release, Valkey 9.0 brings innovation, long-requested features, and improvements to classic features updated for today’s workloads. Read on to find out all the team packed into this release.
Atomic Slot MigrationsAtomic slot migrations fundamentally changes how Valkey migrates data from node-to-node inside the cluster. Prior to Valkey 9.0, data migrated in the c [...]
The upcoming Valkey 9.0 release brings major improvements in the resilience of large clusters, enabling scaling to 2,000 nodes and achieving over 1 billion requests per second, all while ensuring bounded recovery time. In this blog post, we provide an overview of how the Valkey clustering system works, along with the architectural improvements and rigorous testing that made this level of scale p [...]
Vector search for Amazon ElastiCache is now generally available. Customers can now use ElastiCache to index, search, and update billions of high-dimensional vector embeddings from popular providers like Amazon Bedrock, Amazon SageMaker, Anthropic, and OpenAI with latency as low as microseconds and up to 99% recall.
Key use cases include semantic caching for large language mode

On October 3rd, 2025, Redis released details on CVE-2025-49844.
This particular vulnerability could allow an authenticated user to obtain remote code execution using a specially crafted Lua script.
This affects all Redis and Valkey versions that have Lua scripting support.
This issue is resolved in:
When you run infrastructure at scale, the smallest efficiencies compound into massive savings. Sorted sets (ZSETs) are the backing data structure for far more than leaderboards. They're used for time‑ordered feeds, priority queues, recommendation rankings and more. Each entry carries per‑item overhead; when you're inserting tens of millions of items, those bytes accumulate into gigabytes. The la [...]
One of the great strengths of Valkey has always been its built-in ability to expire keys. This simple but powerful mechanism lets developers keep their datasets fresh, automatically clear caches, or enforce session lifetimes without additional logic. But there has always been one limitation: expiration worked at the level of whole keys. If you stored multiple fields in a hash, you could set a TT [...]
Open source key-value database Valkey is set for its ninth iteration next month, promising improved resource optimization and availability.…
[...]If you explore Valkey’s documentation you might run across a feature called ‘numbered databases’ which allows you to separate the keyspace into (by default) 16 different databases. Digging into this feature reveals tantalizing ways to avoid key prefixing, house different workloads together on Valkey, and even perform patterns that are otherwise clunky. However, if you’ve done more research outsi [...]
Discover how Open Source Pogocache outperforms Redis and Memcache, offering enhanced caching solutions for your applications. Explore its features today!
The post Open Source Pogocache Pushes Beyond Redis and Memcache appeared first on Linux Today.
[...]Valkey was founded just over a year ago to keep high-performance key/value storage in the open source community: free from vendor lock-in and restrictive licenses. Backed by contributors like AWS, Google Cloud, Ericsson, Oracle, Alibaba, Huawei, Tencent, Percona, Aiven, Heroku, Verizon, Chainguard, and Canonical, the project shows how “free” in open source depends on investment: time, talent, an [...]
Redis 8.2 is FOSS again, albeit under a different license, and has multiple performance enhancements. Meanwhile, Redis 7.2, the last of the old FOSS versions, is nearing its end of life. New version, or new Valkey?…

We are excited to introduce the preview release of valkey-swift, a new Swift based client library for Valkey.
The ClientValkey-swift is a modern swift client built with Swift concurrency in mind. Using Valkey from Swift lets you take advantage of a strongly typed API, Swift's memory and data race safety guarantees, as well as maintaining a very light memory footprint. The API uses struct [...]
Amazon ElastiCache now offers Extended Support for ElastiCache versions 4 and 5 for Redis OSS, allowing customers to maintain critical workloads on these versions for up to three years beyond the standard support end date. This new offering addresses the needs of customers who require additional time to plan and execute version upgrades due to application dependencies or large-scale deployment c [...]
Amazon ElastiCache now supports Bloom filters as a new data type in ElastiCache version 8.1 for Valkey and above. Bloom filters are a space efficient probabilistic data structure that lets you quickly check whether an item is possibly in a set. This new feature is fully compatible with the valkey-bloom module and API compatible with the Bloom filter command syntax of the Valkey client libraries, [...]
Today, Amazon ElastiCache announces support for Valkey 8.1, bringing the latest innovations from the Valkey open source project into ElastiCache for Valkey, including new capabilities, performance improvements, and observability enhancements. These improvements will help developers to increase an application’s responsiveness while reducing infrastructure cost for in-memory workloads.
