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 […]

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. […]

When it comes to optimizing MongoDB, compression is a key lever for reducing storage footprint, minimizing I/O bottlenecks, and even speeding up data transfer. The benefits are clear: significant cost savings and the ability to handle more data within the same […]
This post was originally published in June 2024 and was updated in March 2025. MongoDB’s flexibility and speed make it a popular database choice, but as your data grows, managing and querying massive datasets can become challenging. This is where partitioning, also known as sharding, comes to the rescue. Partitioning strategically divides your data collection […]
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 […]
