And here we go again: here is another term. We are still debating about the real meaning of Cloud and if a database fits in IaaS, PaaS, SaaS or in a combination of all three, and now we experience another wave of change. To be fair, the term Fog Computing has been around for quite some time, but it has never enjoyed the popularity of its buddy “the Cloud”.
Is Fog Computing another pointless renaming of well known technologies and IT infrastructures? Or is it a real new thing that Systems and Database Administrators should look at, study and embrace? My intent here is not to support one side or the other, but simply to instil a few thoughts that may turn handy in understanding where the IT market is going, and more specifically where MySQL can be a good fit in some of the new …

In a previous post, I talked about the existence of a CREATE TABLE that is crashing MySQL up to versions 5.5.58, 5.6.38 and 5.7.20, and MariaDB up to version 5.5.57, 10.0.32, 10.1.26 and 10.2.7.  I hope you upgraded (or can mitigate this problem in another way) as I am now publishing the CREATE TABLE of death.

The first thing to clarify about the CREATE TABLE of death is that it is not a bug in

As last year, we will take advantage of the mass presence of our engineers during FOSDEM to organize a MySQL Day once again.

The Agenda is not yet known, but save the date and schedule your trip to Brussels keeping in mind that Friday February 2nd 2018, there will be a full day dedicated to MySQL !

More to come soon but don’t forget to register !

Dear MySQL users,

I’m glad to announce that MySQL X DevAPI extension for PHP 8.0.3 has been recently released!

If for some reason you don’t know what this is all about, then in short the MySQL X DevAPI for PHP add support for the new X DevAPI in PHP, and it’s released as an extension to the language. The X DevAPI enables application developers to write code that combines the strengths of the relational and document models –MySQL as a Document Store– using a modern NoSQL-like syntax that does not assume previous experience writing traditional SQL.

For general documentation about how to get started using MySQL as a document store, see “Using MySQL as a Document Store”.

Download the extension.

Sometimes it can be useful to take a step back and look at the world from a bit larger distance than usual. So in this blog, I will take a look at the high level architecture of MySQL Server.

Info This is meant as a simplified overview and does not include all details. Overview of the MySQL Server Architecture

For the discussion I will be referring to the the following figure that shows some of the features and plugins of MySQL. Orange boxes are available both for the community version and the commercial (enterprise) version, whereas red means the plugin is exclusive for the commercial version. Ellipsoid elements are plugins, …

The Docker version of the distributions are often quite old. On Ubuntu 16.04 for example:

shell> docker --version 
Docker version 1.13.1, build 092cba3

But the current docker version is 17.09.0-ce (2017-09-26). It seems like they have switched from the old version schema x.y.z to the new year.month.version version schema in February/March 2017.

In ClusterControl 1.5 we added a support for the MySQL NDB Cluster 7.5. In this blog post, we’ll look at some of the features that make ClusterControl a great tool to manage MySQL NDB Cluster. First and foremost, as there are numerous products with “Cluster” in their name, we’d like to say couple of words about MySQL NDB Cluster itself and how it differentiates from other solutions.

Hurry up – the call for papers (CFP) for FOSDEM 2018 ends December 1, 2017. I highly recommend submitting as its a really fun, free, and technically-oriented event.

Don’t forget that the CFP for Percona Live Open Source Database Conference 2018 in Santa Clara closes December 22, 2017, so please also consider submitting as soon as possible. We want to make an early announcement of the talks, so we’ll definitely do the first pass even before the CFP date closes.
