New Member of the Cluster API Family: The Native Node.js Connector

MySQL Cluster 7.3 went GA yesterday and with it came a new member of the MySQL Cluster API family: mysql-js – a native Node.js connector. mysql-js uses the NDB API to connect directly to the data nodes which improves performance compared to executing queries through the MySQL nodes.

For an introduction to mysql-js and installation instructions I will recommend taking a look at the official API documentation and Andrew Morgan’s blog; the latter also has an overview of the new features in MySQL Cluster 7.3 in general.

To get a feel for how the new API works, I went ahead and created …

Foreign Keys in MySQL Cluster

Foreign Key constraints between tables

The newly announced GA of MySQL Cluster 7.3 (7.3.2) builds upon second DMR (7.3.1 m2) released earlier in the year which added Foreign Keys to MySQL Cluster. Foreign Keys is a feature requested by many, many people and has often been cited as the reason for not being able to replace InnoDB with MySQL Cluster when they needed the extra availability or scalability.

Note that this post is an up-version of the original – and was first published with the 7.3 labs release in June 2012.

What’s a Foreign Key

The majority of readers who are already familiar with Foreign Keys can skip to the next section.

Foreign Keys are a way of implementing relationships/constraints between columns in different tables. For example, in the above figure, we want to make sure …

MySQL Cluster 7.3 GA – Includes MySQL Cluster Auto-Installer

MySQL Cluster 7.3 has just been declared Generally Available (and with it the new MySQL Cluster Auto-Installer) – download it from here.

Deploying a well configured cluster has just got a lot easier! Oracle have released a new auto-installer/configurator for MySQL Cluster that makes the processes extremely simple while making sure that the cluster is well configured for your application. A single command launches the web-based wizard which then steps you through configuring the cluster; to keep things even simpler, it will automatically detect the resources on your target machines and use these results together with the type of workload you specify in order to determine values for the key configuration parameters.

For a broader view of what is being released – check out this …

Choosing a MySQL HA Solution – MySQL Webinar: June 5

Selecting the most appropriate solution for a MySQL HA infrastructure is as much a business and philosophical decision as it is a technical one, but often the choice is made without adequately considering all three perspectives.  When too much attention is paid to one of these aspects at the cost of the others, the resulting system may be over-engineered, poorly-performing, and/or various other flavors of suboptimal.

On Wednesday, June 5, at 10 a.m. PDT (1700 UTC), I will be presenting a webinar entitled, Choosing a MySQL HA Solution, in which we’ll explore the topic of MySQL HA from each of these perspectives.  The goal will be to motivate your thinking about HA in a holistic fashion and help …

The MySQL Cluster storage engine

This is one close to my heart. I’ve recently written on other storage engines: Where are they now: MySQL Storage EnginesThe MERGE storage engine: not dead, just resting…. or forgotten and The MEMORY storage engine. Today, it’s the turn of MySQL Cluster.

Like InnoDB, MySQL Cluster started outside of MySQL. Those of you paying attention at home may notice a correlation between storage engines not written exclusively for MySQL and being at all successful.

NDB (for Network DataBase) started inside Ericsson, originally written in a language called …
