“The only workload that matters is my production workload” (for all values of “my”). So you can manage this responsibility, SCARY is a software tool which aims to take the uncertainty out of change; software, configuration and hardware changes. This is very early in development, but projects have to start somewhere.
SCARY takes a read view of the production database query execution, and does the equivalent query on a copy of the production database, that has differences. The query speed, query plan, data result (eventually) will be recorded along with what went on in production.

Have you ever wondered how to get started with contributions to the world’s most popular open source database? Did you have a problems with building and configuring from source code, writing the contribution patch and testing the server with use of mysql-test-run (mtr) framework afterwards?
How to make your patch visible to other developers?
In this section we will go through each step in this process from getting the latest source code, testing the server and writing your first contribution with the live demo!
Let’s get started! Anel Husakovic (https://mariadb.org/about/staff/anel-husakovic/) – is going to talk about it all at our New York Unconference 23d-24th of February …

Here is a quick tip for any developer who might want to test if the latest development version of MariaDB installs/upgrades. Traditionally, developers seem to have a bunch of virtual machines lying around which they use to test MariaDB installation and upgrade related things. Snapshotting virtual images, keeping them up-to-date, starting, stopping etc. takes a lot of time and does not feel very convenient.
A much faster option would be to use pristine Docker images for every test. Docker images however normally only run one process and thus do not simulate a complete operating system and lack vital things like systemd interactions. …

My fellow testers and others who run RQG tests on MySQL flavors might be interested in some additions that are being used for MariaDB testing. While none of them is a major breakthrough, maybe they will make somebody’s life a little easier.
RQG Introduction
A quick introduction for those who have never heard of RQG, but are still curious what this blog post is about.
RQG stands for Random Query Generator, also known as randgen — an open-source product, available under the GPL v2 license. Quoting its home page on Launchpad, it is a “pseudo-random data and query generator that can be used to test any Perl DBI, JDBC or ODBC-compatible SQL server, in particular MySQL, but also JavaDB and PostgreSQL”. …
