Fernando Laudares Camargos
Fernando Laudares Camargos joined Percona in early 2013 after working 8 years for a Canadian company specialized in offering services based in open source technologies. Fernando's work experience includes the architecture, deployment and maintenance of IT infrastructures based on Linux, open source software and a layer of server virtualization. From the basic services such as DHCP & DNS to identity management systems, but also including backup routines, configuration management tools and thin-clients. He's now focusing on the universe of MySQL, MongoDB and PostgreSQL with a particular interest in understanding the intricacies of database systems and contributes regularly to this blog. You can read his other articles here.

Using Loki and Promtail to Display PostgreSQL Logs From a Kubernetes Cluster in PMM

This is a follow-up to my colleagues Nickolay and Phong’s Store and Manage Logs of Percona Operator Pods with PMM and Grafana Loki and Agustin’s Turbocharging Percona Monitoring and Management With Loki’s Log-shipping Functionality blog posts. Here, I focus on making PostgreSQL database logs from a Kubernetes cluster deployed with the Percona Operator for PostgreSQL […]

PostgreSQL Backup Strategies for Enterprise-Grade Environments

This blog was originally written in September 2018 and was updated in June 2023. In this post, we cover the methods used to achieve an enterprise-grade backup strategy for the PostgreSQL cluster. In setting up our demonstration system, we use pg_basebackup and continuous archiving. The size of the database and your database environment—if it is […]

MySQL Data Caching Efficiency

A shared characteristic in most (if not all) databases, be them traditional relational databases like Oracle, MySQL, and PostgreSQL or some kind of NoSQL-style database like MongoDB, is the use of a caching mechanism to keep (a copy of) part of the data in memory. The reasoning behind it is very simple: accessing data from […]

PostgreSQL Sharding: An Overview and MongoDB Comparison

This post was originally published in 2019 and was updated in 2023. I presented at Percona University São Paulo about the new features in PostgreSQL that allow the deployment of simple shards. I’ve tried to summarize the main points in this post, as well as provide an introductory overview of sharding itself. Please note I […]

PMM Now Supports Monitoring of PostgreSQL Instances Connecting With Any Database (Name)

The recent release of Percona Monitoring and Management 2.25.0 (PMM) includes a fix for bug PMM-6937: before that, PMM expected all monitoring connections to PostgreSQL servers to be made using the default postgres database. This worked well for most deployments, however, some DBaaS providers like Heroku and DigitalOcean do not provide direct access to the […]

Inspecting MySQL Servers Part 4: An Engine in Motion

The combination of the information obtained from the “pt-summaries” discussed in the previous posts of this series (Part 1: The Percona Support Way, Part 2: Knowing the Server, Part 3: What MySQL?) helps us come up with the first impression of a MySQL server. However, apart from the quick glance we get at two samples […]

Inspecting MySQL Servers Part 3: What MySQL?

In the previous post of this series, we looked at the hardware specifications and operating system settings of the host server through the lenses of a pt-summary report. Now that we know the foundation on which the database is running, we can turn our focus to MySQL itself. The second of our triad of tools […]

A Tale About Migrating a PostgreSQL Database Between Different DBaaS Providers

We recently helped migrate a production PostgreSQL database running on a given DBaaS platform… to another DBaaS platform. When it comes to vendor “lock-in”, some providers are easier (and even friendlier) to deal with than others, but it is never a straightforward process. While in a traditional environment we would usually approach this problem by […]

Resolving MongoDB Stack Traces

When a MongoDB server crashes you will usually find what is called a “stack trace” in its log file. But what is it and what purpose does it have? Let’s simulate a simple crash so we can dig into it. Crashing a test server In a test setup with a freshly installed MongoDB server, we […]
