HowTo Video: Using MySQL ASP.NET MVC Project Wizard

MySQL for Visual Studio 1.2.x recently became a GA version. One of the main features included in this version was the new MySQL ASP.NET MVC Wizard. This wizard allows the creation of a new ASP.NET MVC application using a MySQL existing database and a data entity model with Entity Framework 5 or 6 version. In this video you will see this feature in action and will show you how to generate a complete MVC application that includes authentication, registration and browsable pages for each table in your MySQL database without any code needed.

Building a MariaDB Galera Cluster with Docker

There’s been a lot of talk about Docker for running processes in isolated userspace (or the cloud for that matter) lately. Virtualization is a great way to compartmentalise applications  and processes however the overhead of virtualization isn’t always worth it – in fact, without directly attached storage IO degradation can seriously impact performance. The solution? Perhaps Docker… With its easy to use CLI as well as the lightweight implementation of cgroups and kernel namespaces.

Without further ado, I present a step-bystep guide on how to build a MariaDB 5.5 Galera Cluster on Ubuntu 14.04. The same guide can probably be applied for MariaDB versions 10+ however I’ve stuck with 5.5 since the latest version of MariaDB Galera Cluster is still in beta.

So we start off with modifying the “ufw” firewall policy to accept forwarded packets and perform a “ufw” service restart for good measure:

Special Aspects of Sphinx SE Support

At the moment, dbForge Studio for MySQL allows you to create a connection to Sphinx Search Engine. Due to technical restrictions, a warning message appears in some cases. The reason the message appears is because, there is no possibility to define that the connection happens to  Sphinx SE. We requested the Sphinx SE developers team to fix […]

OpenStack Trove Day 2014 Recap: MySQL and DBaaS

OpenStack Trove Day

I just returned from a week in Cambridge, Massachusetts where I was attending the OpenStack Trove Day and the Trove mid-cycle meetup, both sponsored by the great folks at Tesora.

I am relatively new to the OpenStack and Trove arenas so this was a fantastic opportunity for me to learn more about the communities, the various components within OpenStack, and what part Trove plays. I found the entire event very worthwhile – I met a lot of key people in the community, learned more about Trove and its potential, and in general felt a great energy and excitement surrounding Trove and OpenStack as a whole.

There were more than 120 attendees at Trove Day. That is almost four times the initial estimate! I …

Trawling the binlog with FlexCDC and new FlexCDC plugins for MySQL

Swanhart-Tools includes FlexCDC, a change data capture tool for MySQL. FlexCDC follows a server’s binary log and usually writes “changelogs” that track the changes to tables in the database. I say usually because the latest version of Swanhart-Tools (only in github for now) supports FlexCDC plugins, which allow you to send the updates to a remote data source, or to any other place of your liking.  You can find out more about FlexCDC basics in a previous blog post.

Please note that FlexCDC still needs to have source and destination instances defined in the configuration, even when using plugins.  This is because the FlexCDC state (how much into …

Changes in Configuration of Global Variables between MySQL 5.6.20 and MySQL 5.7.4 “Milestone 14”

While doing some testing (that I published later here) on the still-in-development MySQL 5.7 I wanted to do some analysis on the configuration to see if the changes in performance were due to the code changes or just to the new MySQL defaults (something that is very common in the migration from 5.5 to 5.6 due to the default transaction log size and other InnoDB parameters). This is a quick post aiming to identify the global variables changed between these two versions.

You could tell me that you could just read the release notes, but my experience (and this is not an exception, as you will see) …
