Percona.Connect London 2025 brought the open-source database community together for a half-day of learning and collaboration. The event focused on providing practical, technical insights for DBAs, DevOps engineers, and developers. The main takeaway was clear: Stability, Openness, and Automation are essential for modern, large-scale data infrastructure.
Top Discussions & Key Takeaways 1. [...]Engineering wins look dramatic from the outside. From the inside, they're months of small, unglamorous changes - the kind nobody celebrates until they compound into something that looks impossible.

[...]Few things make SREs more nervous than rebalancing a cache cluster. You know the feeling. You add a node, trigger a rebalance, and suddenly latency graphs start jumping. It’s a familiar risk of the job, especially when your cache sits between your users and your database. A small configuration mistake here can suddenly unleash a […]

Aiven for Valkey™ version 8.1 is now available on the Aiven Platform. It introduces multiple improvements on top of version 8.0, including:
Performance improvements
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 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 [...]
Valkey 8.1 uses 28% less memory than Redis 8.2 in our 50M sorted set benchmark. See the throughput and memory data from real-world hyperscale testing.

[...]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 [...]

[...]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 [...]
