Fernando Laudares CamargosKubernetes has been a big trend for a while now, particularly well-suited for microservices. Running your main databases on Kubernetes is probably NOT what you are looking for. However, there’s a niche market for them. My colleague Stephen Thorn did a great job explaining this in The Criticality of a Kubernetes Operator for Databases. If […]
A few days ago, a customer got in touch asking how they could use Percona Monitoring and Management (PMM) to monitor the roles played by each node in an InnoDB cluster. More specifically, they wanted to check when one of the nodes changed its role from Primary to Secondary, or vice-versa. PMM allows for a […]
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 […]
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 […]

When you need to upgrade your PostgreSQL databases, there are a number of options available to you. In this post we’ll take a look at how you can upgrade PostgreSQL versions using pg_upgrade, a built-in tool that allows in-place upgrade of your software. Using pg_upgrade allows you, potentially, to minimize your downtime, an essential consideration […]
When you need to upgrade PostgreSQL, there are a variety of approaches that you can use. To avoid application downtime, then not all of the options to upgrade postgres are suitable. When avoiding downtime is essential, then you might consider using replication as a means of upgrade, and depending on your scenario, you can choose […]
ARM processors have been around for a while. In mid-2015/2016 there were a couple of attempts by the community to port MongoDB to work with this architecture. At the time, the main storage engine was MMAP and most of the available ARM boards were 32-bits. Overall, the port worked, but the fact is having MongoDB […]
There are several approaches to assess when you need to upgrade PostgreSQL. In this blog post, we look at the option for upgrading a postgres database using pg_dumpall. As this tool can also be used to back up PostgreSQL clusters, then it is a valid option for upgrading a cluster too. We consider the advantages […]

Hello everyone, and thank you to those that attended our webinar on Building an Enterprise-grade PostgreSQL setup using open source tools last Wednesday. You’ll find the recordings of such as well as the slides we have used during our presentation here. We had over forty questions during the webinar but were only able to tackle […]
You may be aware that the new major version of PostgreSQL has been released today. PostgreSQL 11 is going to be one of the most vibrant releases in recent times. It incorporates many features found in proprietary, industry-leading database systems, further qualifying PostgreSQL as a strong open source alternative. Without further ado, let’s have a […]
This is the last post in our series on building an enterprise-grade PostgreSQL set up using open source tools, and we’ll be covering monitoring. The previous posts in this series discussed aspects such as security, backup strategy, high availability, connection pooling and load balancing, extensions, and detailed logging in PostgreSQL. Tomorrow, Wednesday, October 10 at 10AM EST, […]
The release of MySQL 8.0 has brought a lot of bold implementations that touched on things that have been avoided before, such as added support for common table expressions and window functions. Another example is the change in how AUTO_INCREMENT (autoinc) sequences are persisted, and thus replicated.
In this penultimate post from our series on building an enterprise-grade PostgreSQL environment we cover the parameters we have enabled to configure detailed logging in the demo setup we will showcase in our upcoming webinar. Detailed logging in PostgreSQL and log analyzer Like other RDBMS, PostgreSQL allows you to maintain a log of activities and error […]
In this current series of blog posts, we have been discussing various relevant aspects when building an enterprise-grade PostgreSQL setup, such as security, back up strategy, high availability, and different methods to scale PostgreSQL. In this blog post, we’ll get to review some of the most popular open source extensions for PostgreSQL, used to expand […]
In the previous blog posts in this series, we’ve covered some of the essential aspects of an Enterprise-grade solution: security, high availability, and backups. Another important aspect is the scalability of the solution: as our application grows how do we accommodate an increase in traffic while maintaining the quality of the service (response time)? The […]
High availability (HA) and database replication is a major topic of discussion for database technologists. There are a number of informed choices to be made to optimize PostgreSQL replication so that you achieve HA. In this post we introduce an overview of the topic, and cover some options available to achieve high availability in PostgreSQL. […]
In this post, we review how you can build an enhanced and secure PostgreSQL database environment using community software. We look at the features that are available in PostgreSQL that, when implemented, provide improved security. As discussed in the introductory blog post of this series, in our webinar of October 10, 2018 we highlight important […]
