The latest release of the Percona Operator for MongoDB, 1.22.0 is here. It brings automatic storage resizing, HashiCorp Vault integration for system user credentials, better integration with service meshes, improved backup and restore options, and more. This post walks through the highlights and how they can help your MongoDB deployments on Kubernetes. Percona Operator for MongoDB […]

At Percona, open source is not just something we use. It is who we are. From our earliest days, our mission has been simple and consistent: make open source databases better for everyone. That mission guides our product decisions, our business model, and how we engage with the community. Today, I want to share an […]

At Percona, we’ve always believed that the best software isn’t built in a vacuum—it’s built in the open, fueled by the real-world challenges of the people who use it every day. Today, I’m excited to walk you through a journey that perfectly illustrates this: the road from a JIRA ticket to native Alibaba Cloud Object […]

Remember when Percona significantly improved query processing time by fixing the optimizer bug? I have described all the details in More Performant Query Processing in Percona Server for MySQL blog post. This time, we dug deeper into all the ideas from Enhanced for MySQL and based on our analysis, we proposed several new improvements. All […]

Deploying databases on Kubernetes is getting easier every year. The part that still hurts is making deployments repeatable and predictable across clusters and environments, especially from Continuous Integration(CI) perspective. This is where PR-based automation helps; you can review a plan, validate changes, and only apply after approval, before anything touches your cluster.  If you’ve ever […]

In 2025, the Percona Operator for PostgreSQL put most of its energy into the things that matter when PostgreSQL is running inside real Kubernetes clusters: predictable upgrades, safer backup and restore, clearer observability, and fewer surprises from image and HA version drift.  Backups and restores got more resilient and more controllable In March, Operator 2.6.0 […]

Migrating mission-critical databases is often compared to changing the engines on a plane while it’s in mid-flight. For MongoDB users, this challenge has been historically steep, often involving complex workarounds or proprietary tools that keep you locked into a specific ecosystem. Today, we are thrilled to announce the General Availability of Percona ClusterSync for MongoDB […]

In this blog post, we will be discussing the PXC Replication Manager script/tool which basically facilitates both source and replica failover when working with multiple PXC clusters, across different DC/Networks connected via asynchronous replication mechanism. Such topologies emerge from requirements like database version upgrades, reporting or streaming for applications, separate disaster recovery or backup solutions, […]

At Percona, our mission has always been to provide the community with truly open-source, enterprise-class software. A critical part of that mission is ensuring that when security vulnerabilities arise in the upstream ecosystem, we respond with the urgency and transparency our users expect. As many in the MongoDB community are now aware, a security vulnerability—CVE-2025-14847, […]

For decades, we’ve accepted a painful compromise: if you wanted logic inside the database, you had to write SQL/PSM (Persistent Stored Modules). It’s clunky, hard to debug, and declarative by nature, making it terrible for algorithmic tasks. That ends with Percona Server 8.4.7-7. We are introducing JS Stored Programs as a Tech Preview. Unlike Oracle’s […]
