If you’re running enterprise applications, you might be facing a common dilemma: cloud solutions offer great features, but regulatory constraints and data sovereignty laws might prevent you from using them fully. In fact, about 60% of enterprises struggle with this exact problem. While cloud computing delivers scalability and convenience, your organization might require on-premises or […]

Everyone knows that MongoDB has FTDC (Full-Time Diagnostic Data Capture), which helps MongoDB engineers analyze server behavior, tune parameters, and conduct forensic work when issues occur within their clusters. Here at Percona, we’ve been using the Keyhole tool for a while, and it’s great! It’s very useful for tuning parameters or analyzing what happened at […]
If you’re using MongoDB, whether it’s the Community Edition, Enterprise Advanced, or Atlas, you’ve probably asked yourself at some point: what is this actually costing us? And the answer isn’t always easy to pin down. The reality is that there’s no one-size-fits-all price tag. Your infrastructure, usage patterns, and team setup all factor in. That’s […]
One of our customers recently reported that MongoDB’s diagnostic metrics—collected via FTDC (Full-Time Diagnostic Data Capture)—had stopped updating. As a result, no metrics were being collected, either through diagnostic data files or the getDiagnosticData command. Key metrics such as uptime were no longer progressing. While the cluster remained fully operational, the lack of observability introduced a […]
It is generally known and established that different database versions provide different sets of features and performance rates. Along with the binary versions, MongoDB has a property called Feature Compatibility Value, which allows administrators to run a binary version without enabling any features that are incompatible with the previous one. This property is generally helpful […]
If you’ve tried running MongoDB on Kubernetes, you’ve likely run into some unique challenges. Stateful workloads like replica sets and sharded clusters can be messy in containers, and things that should be easy, like backups, scaling, failovers, and upgrades, suddenly take more time and attention than they should. That’s exactly what good MongoDB Operators are […]
This post was originally published in January 2021 and was updated in March 2025. Adding more memory to your MongoDB deployment is a common vertical scaling strategy. But simply increasing RAM isn’t enough; you also need to tune MongoDB’s WiredTiger cache to effectively utilize that new memory. This post in our MongoDB 101 series will […]
Recognizing a gap in the availability of straightforward tools for MongoDB benchmarking, particularly those that do not require complex compilation, configuration, and intricate setups, I developed MongoDB Workload Generator. The aim was to provide MongoDB users with an accessible solution for effortlessly generating realistic data and simulating application workloads on both sharded and non-sharded clusters. […]
This blog was originally published in August 2022 and was updated in April 2025. In this blog, we’ll examine the increasingly popular practice of running MongoDB on Kubernetes. We will explore various solutions and approaches to this setup, from direct deployments as a stateful application to utilizing specialized operators and considering cloud-based solutions, guiding you […]
This post was originally published in April 2023 and was updated in April 2025. When asked “Is MongoDB open source?”, at Percona, our definitive answer is “no.” Let’s start with this: MongoDB is accurately referred to as source-available software. Whereas many open source software offerings — like the community version of MySQL — use the […]
This blog was originally published in September 2020 and was updated in April 2025. As a MongoDB user, ensuring your data is safe and secure in the event of a disaster or system failure is crucial. That’s why it’s essential to implement effective MongoDB backup best practices and strategies. Regular database backups are the cornerstone […]
This post was originally published in April, 2023 and was updated in April, 2025. Binary Javascript Object Notation (BSON) is a binary-encoded serialization of JSON documents. JSON is easier to understand as it is human-readable, but compared to BSON, it supports fewer data types. BSON has been extended to add some optional non-JSON-native data types, […]
Let’s be honest: Getting MongoDB up and running quickly in the cloud sounds fantastic. Services like MongoDB Atlas promise easy deployment, automated scaling, and hands-off management on AWS, Azure, and GCP. For teams looking to shed operational burdens, the appeal is tempting. Click a few buttons, get a database… what’s not to like? However, as […]
Percona commits to delivering robust, enterprise-grade, and community-driven software for MongoDB. We build our databases and tools to meet evolving data needs. As MongoDB continues to evolve, we’ve updated and clarified our release strategy for the Percona Software for MongoDB suite. This suite includes: Percona Server for MongoDB (PSMDB) Percona Backup for MongoDB (PBM) Percona […]
MongoDB has always made it relatively easy to scale horizontally, but with version 8.0, the database takes a significant step forward. If you’re working with large datasets or high-throughput applications, some of the changes in this release will make your life a lot easier — and your architecture cleaner. Let’s take a look at some […]
Want to spin up fully functional environments for trying out Percona Server for MongoDB, complete with Percona’s backup and monitoring solutions in minutes? We recently made our automation framework publicly available, which makes it easy to create and manage these environments either on your local machine or in public cloud environments. Why we built this […]
When running MongoDB replica sets in containerized environments like Docker or Kubernetes, making nodes reachable from inside the cluster as well as from external clients can be a challenge. To solve this problem, this post will explain the Horizons feature of Percona Server for MongoDB. Let’s start by looking at what happens behind the scenes […]
This post explains how to perform a Rolling Index Build on a Kubernetes environment running Percona Operator for MongoDB. Why and when to perform a Rolling Index Build? Building an index requires: CPU and I/O resources Database locks (even if brief) Network bandwidth If you have very tight SLAs or systems that are already operating […]
On behalf of the entire Percona product team for MongoDB, I’m excited to announce a significant enhancement to Percona Server for MongoDB: File Copy-Based Initial Sync (FCBIS). It is designed to accelerate your large-scale database deployment with a more efficient method for initial data synchronization. FCBIS reduces the time and resources required by the initial […]
As enterprise software vendors race toward proprietary cloud ecosystems, some features long relied upon by businesses are being quietly deprecated. One recent example is MongoDB Enterprise Advanced and Atlas dropping support for LDAP authentication, a foundational identity protocol for countless organizations. At Percona, we’re taking a different path. We’ve supported LDAP in Percona Server for MongoDB for […]
