♦Modern applications often rely on multiple services to provide fast, reliable, and scalable responses. A common and highly effective architecture involves an application, a persistent database (like MySQL), and a high-speed cache service (like Valkey). In this guide, we’ll explore how to integrate these components effectively using Python to dramatically improve your application’s performanc [...]

Engineers operating large-scale systems face a consistent challenge: what works at moderate scale often breaks in subtle ways as systems grow. Recently, contributors and platform teams gathered at the Unlocked Conference to compare notes on what actually happens when Valkey is under real production load.

What follows are high-level observations from the day — directional insights that kep [...]

This release improves PrivateLink management with enhanced GCP PrivateLink connection approval through the new psc_connection_id field in aiven_gcp_privatelink_connection_approval. It lets you select specific connections when multiple PSC connections exist for the same service. Additionally, privatelink_connection_id support has been added across all servic [...]

In this post, we talk about the benefits of caching in generative AI applications. We also elaborated on a few implementation strategies that can help you create and maintain an effective cache for your application. [...]

As we kick off 2026, it’s a great moment to pause, reflect, and celebrate what the Valkey project and its community has accomplished together. This past year marked an important chapter for Valkey, one defined by growth, collaboration, and a shared commitment to building an open, high-performance key-value store for everyone.

2025 Key Milestones

This past year brought meaningful progress [...]

This release introduces significant updates including Kubernetes v0.28 support. The operator now requires Go 1.20+.

A major change in this version is the complete removal of the Redis kind and controller from the operator, as Redis has reached end of life. Use Valkey instead for all caching services.

Key enhancements in this release include:

• Enhanced backup ca [...]

Tail latencies are where promises break. You can have a system that's fast 99% of the time, but that 1% is what users remember.

Last year, Bitnami changed how it publishes and supports many container images and Helm charts (see charts issue #35164, charts issue #36215, and the Bitnami Secure Images announcement). Some images move behind new terms, and older tags may not be available as before.

If your pipelines pull Bitnami charts or images during deploys, you may experience significant operational issues: rollout [...]

The Valkey™ JSON module is now available for all Aiven for Valkey™ services. This module extends Valkey features with advanced JSON data handling capabilities.

Key features

• Native JSON storage: Store JSON documents as values directly in Valkey
• JSONPath queries: Query JSON documents using standard JSONPath syntax
• Atomic updates: Make atomic u [...]

Most of the production security incidents I've helped debug started with misconfigurations rather than zero-days or sophisticated exploits.

Security misconfiguration ranks as A05 in the OWASP Top 10:2021, with 90% of applications tested showing some form of misconfiguration. That's staggering. And when it comes to infrastructure like Valkey, the stakes are even higher - your cache often s [...]

This version of the Aiven Terraform Provider adds write-only password support to service user resources, including aiven_kafka_user, aiven_mysql_user, aiven_opensearch_user, aiven_pg_user, and aiven_valkey_user. You can now manage passwords for these service users securely without storing them in your state file by using the new

We are excited to announce the launch of Aiven for Valkey™ clustering in limited availability. This managed solution provides scalable, distributed in-memory data storage with built-in high availability.

Aiven for Valkey clustering automatically partitions your data across multiple nodes (shards), enabling you to handle larger datasets and higher traffic loads than a single-node deployment [...]

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

• New hashtable implementation: Reduces the average memory needed for key-value pairs and the number of random memory accesses. It also improves throughput by approximately 10% on pipeline workloads when not using I/O [...]

Valkey 9.0 introduces numbered databases in cluster mode - a subtle change that simplifies multi-tenant design, data isolation, and atomic data updates.

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 [...]

Valkey 9 is the best demonstration of the dream of the open source model. It boosts stability at scale, improves developer experience, and is faster than ever.
