Yesterday I participated to the Oracle Technology Roundtable for Digital Natives in Zurich.

It was a good opportunity to learn more about AI, Cloud and HeatWave with the focus on very trendy features of this product: generative AI, machine learning, vector processing, analytics and transaction processing across data in Data Lake and MySQL databases.

It was also great to share moments with the Oracle and MySQL teams and meet customers which gave feedback and tips about their solutions already in place in this area.

I’ll try to summarize below some key take-away of each session.

AI is not a new topic. But how do we …

Multicloud is a cloud adoption strategy that utilizes services from multiple cloud providers rather than relying on just one. This approach enables organizations to take advantage of the best services for specific tasks, enhances resilience, and helps reduce costs. Additionally, a multicloud strategy offers the flexibility necessary to meet regulatory requirements and increases options for […]

At the beginning of the year, we released MySQL 9.2, the latest Innovation Release. Sorry for the delay, but I was busy with the preFOSDEM MySQL Belgian Days and FOSDEM MySQL Belgium Days. Of course, we released bug fixes for 8.0 and 8.4 LTS, but in this post, I focus on the newest release. Within […]

This blog was originally published in June 2020 and was updated in March 2025. One of the most common support tickets we get at Percona is the infamous “database is running slower” ticket.  While this can be caused by a multitude of factors, it is more often than not caused by a bad or slow […]

As promised, my slides from FOSDEM25 and Pre-FOSDEM MySQL Belgian Days :

• MySQL Scalability & Systems Evaluation Overview 2025 [PDF]
• Profiling MySQL Memory & CPU Usage Directly From MySQL [PDF}

And since I was asked several times about MySQL test case demonstrating glibc-malloc memory fragmentation / leaks -- here are all the details :

Learn about MySQL reserved words, their impact on database design, and how to avoid common errors. Find practical tips, examples, and resources for managing reserved words effectively.

The post MySQL Reserved Words: What You Need to Know  appeared first on Devart Blog.

MySQL Shell is a powerful tool for managing MySQL databases, and one of its most exciting features is the ability to extend its functionality using plugins. If you're a Python developer, you can create custom plugins to automate tasks, add new commands, or
integrate MySQL Shell with other tools. However debugging the python code could be cumbersome for mysql-shell given the python code requires some specific objects available only when running inside the shell. 

In this blog post, we'll walk you through the steps to set up your development environment for creating MySQL Shell plugins in Python while able to modify and debug the mysql-shell itself.

Prerequisites

Before we dive into the setup, ensure you have the following installed on your system:

• MySQL Shell: Download and install MySQL Shell from the official MySQL website.
• Python 3.8 or later: MySQL Shell plugins …

The internet has changed to a place where most protocols like HTTP etc now use secure connections with TLS by default.

While both HTTP and the MySQL Protocol use TLS for secure connections there are still many differences which make it difficult for MySQL to benefit from the same advancements as HTTP has seen in the last so many years.

What is TLS?

TLS stands for Transport Layer Security and is the successor of SSL (Socket Layer Security). SSL and TLS are often used interchangably, while this isn’t correct strictly speaking. What TLS provides is a standardized way to encrypt in transit traffic and authenticate the other end of the connection. TLS when used together with HTTP is known as HTTPS, for secure HTTP.

How TLS works in HTTPS

The client (webbrowser) connects to a server on port 443. Then negitiation is done to agree on what encryption method is to be used. The server presents the client with a …
