It’s 2018. Maybe now is the time to start migrating your network to IPv6, and your database infrastructure is a great place to start. Unfortunately, many legacy applications don’t offer the option to connect to MySQL directly over IPv6 (sometimes even if passing a hostname). We can work around this by using ProxySQL’s IPv6 support which was added in version 1.3. This will allow us to proxy incoming IPv4 connections to IPv6-only database servers.

Note that by default ProxySQL only listens on IPv4. We don’t recommended changing that until this bug is resolved. The bug causes ProxySQL to segfault frequently if listening on IPv6.

In this example I’ll use centos7-pxc57-1 as my database server. It’s running …

The MySQL Document Store became general available (GA) with MySQL 8. One of the nice features of the MySQL Document Store is the X DevAPI that allows you to query the data from a multitude of programming languages using the same API (but while retaining the conventions of the language). The programming languages with support for the X DevAPI includes JavaScript (Node.js), PHP, Java, DotNet, and C++.

I will be using MySQL Connector/Python 8.0.12 for the example in this blog. The example is executed on Microsoft Windows with Python 3.6 installed, but it has also been tested on Oracle Linux 7 with Python 2.7. I do assume that MySQL Connector/Python has been installed. If that is not the case, you can read how to do it in the …

The MySQL database is used in thousands of third-party applications, but what can you do when you want to use MySQL with an application, but that application’s queries or data doesn’t match MySQL’s data type or SQL format?

This post will show you three ways to alter a query or mismatched data when you don’t have control of the application’s source code. Of course, there are hundreds of different ways to do what I am about to show you. In this example, I will show you how to use the MySQL Query Rewrite Plugin along with a trigger to alter the non-conforming data. I will also show you an example of manipulating data with a stored procedure.

Introduction to resource groups in MySQL 8 and dynamical allocation to threads

The post MySQL 8 Resource Group – introduction and dynamic allocation first appeared on Change Is Inevitable.

I wrote MySQL and JSON: A Practical Programming Guide to help developers find their way around the MySQL JSON data type and the supporting functions. The MySQL Documentation on the subject is very good but I had to puzzle through the examples to see how things worked.  I might be a bit 'thick' but good examples always make things easier.  Others seem to have similar difficulties.
