Deploying Percona Operator for MySQL with OpenTaco for IaC Automation
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 […]

Announcing Percona ClusterSync for MongoDB: The Open Source Trail to Freedom
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 […]

The Importance of Realistic Benchmark Workloads
Unveiling the Limits: A Performance Analysis of MongoDB Sharded Clusters with plgm In any database environment, assumptions are the enemy of stability. Understanding the point at which a system transitions from efficient to saturated is essential for maintaining uptime and ensuring a consistent and reliable user experience. Identifying these limits requires more than estimation—it demands […]

Using PXC Replication Manager to Auto Manage Both Source and Replica Failover in Galera-Based Environments
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, […]

Urgent Security Update: Patching “Mongobleed” (CVE-2025-14847) in Percona Server for MongoDB
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, […]

Good Bye Percona Everest, Hello OpenEverest!
Over the past few years, we’ve been building Percona Everest with a clear goal in mind: to deliver a powerful yet approachable DBaaS experience on Kubernetes. Thanks to strong user and customer adoption, Everest has grown into a platform with thousands of production clusters deployed and overwhelmingly positive feedback from the community. As adoption grew, […]

JavaScript Stored Routines in Percona Server for MySQL: A New Era for Database Programmability
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 […]

Running Databases on Kubernetes: A Practical Guide to Risks, Benefits, and Best Practices
As a database administrator, you are the guardian of the company’s most critical asset: its data. You live by performance, reliability, and security, ensuring every change maintains uptime and data integrity. That level of precision takes time, as every update, patch, and configuration is tested before it goes live. Meanwhile, application teams have fully embraced […]

CVE-2025-14847 (MongoBleed) — A High-Severity Memory Leak in MongoDB
A high severity vulnerability, referred to as “mongobleed” (CVE-2025-14847) has been identified in most versions of MongoDB Community and Enterprise editions and MongoDB Atlas. Percona Server for MongoDB (PSMDB) is also affected, since it is based on the upstream MongoDB Community code base. This issue affects all MongoDB server binaries where zlib network compression is […]

Migrate to Freedom: Choosing a Truly Open Source PostgreSQL Operator
Open Source Isn’t What It Used to Be The landscape of open source has undergone significant changes in recent years, and selecting the right operator and tooling for PostgreSQL clusters in Kubernetes has never been more crucial. MinIO, for example, was a widely used open source S3-compatible storage backend. Over the past few years, it has: […]

Building a Multi-Cloud Strategy: Cut Costs, Improve Resilience, and Avoid Lock-In
When you went all-in on the cloud, you were promised agility and savings. But sometimes, the reality feels very different. Instead of simplicity and flexibility, you’re facing higher bills, shrinking options, and a single vendor with all the leverage. You’ve just swapped one form of vendor lock-in for another, and this lack of control can […]

Update Request! New PostgreSQL RPMs Released to Disable Debug Assertions
We recently identified that a batch of our Percona Server for PostgreSQL RPM packages were inadvertently compiled with the debug assertion flag (–enable-cassert) enabled. While these assertions are invaluable for our developers during the testing phase, they are not intended for production use. We have since rebuilt the packages and strongly recommend that all users […]

Percona Operator for MongoDB in 2025: Making Distributed MongoDB More Predictable on Kubernetes
In 2025, the Percona Operator for MongoDB focused on the hardest parts of running MongoDB in Kubernetes: reliable backups and restores, clearer behavior during elections and restores, better observability at scale, and safer defaults as MongoDB 8.0 became mainstream. The year included real course corrections, such as addressing PBM connection leaks and being explicit about […]

Kubernetes Operators Compared: The Key to Scalable, Cost-Efficient Databases
Choosing the right Kubernetes operator is one of those quiet decisions that ultimately defines your database strategy, affecting everything from how easily you automate backups and scaling to how much control you maintain over long-term costs and architecture. But while most operators look similar at first glance, their underlying models yield vastly different outcomes. Some […]

Kubernetes Multi-Cloud Architecture: Building Portable Databases Without Lock-In
Most organizations now run across multiple clouds, pursuing flexibility, better pricing, or regional availability. But while stateless applications move freely, databases often remain stuck. Each cloud provider offers its own managed database service (e.g., RDS, Cloud SQL, Azure Database) with distinct APIs, automation tools, and monitoring layers. Once you commit to one, moving becomes complicated […]

Memory Management in MongoDB 8.0: Testing the New TCMalloc
With MongoDB 8.0, the database engine takes another step forward in performance optimization, particularly in how it manages memory. One of the most impactful changes under the hood is the updated version of TCMalloc (Thread-Caching Malloc), which affects how the server allocates, caches, and reuses memory blocks. For workloads with high concurrency, long-running queries, or […]

Improve Developer Velocity with Kubernetes Databases
Your company has invested heavily in agile development, microservices, and Kubernetes to move faster. Your app teams can spin up a new service in minutes. So why can it still take a week to get a database for it? The bottleneck has shifted. It’s no longer compute; it’s the database. Manual, ticket-based provisioning still dominates, […]
