We’re very pleased to announce that MySQL Cluster 7.3 has gone GA; for a full run-down of the new features and enhancements, take a look at the "MySQL Cluster 7.3 New Features for Internet-Scale Performance with Carrier-Grade Availability" white paper but this post will focus on just one of the features – the MySQL Cluster JavaScript Driver for Node.js. The post will step you through setting everything up so that you can get your first Node.js code reading and writing from MySQL Cluster.

Background

MySQL Cluster is a distributed, shared nothing database that provides linear scalability, 99.999% availability and high read/write throughput with low latency. SQL is …

I wanted install MySQL 5.7.1 (1st Milestone Release) on Windows 7 and test it out a bit, so I did, and since things didn’t go as smooth as expected, I thought I’d share my experience, in case anyone else runs into the same issues.

I downloaded the .msi (mysql-5.7.1-m11-winx64.msi) from http://dev.mysql.com/downloads/mysql/ (then click the “Developmental Releases” tab) and installed it following the prompts. That seemed to complete fine, which was great. However, that was it – and not in a good way. I mean, the “installer” basically only unpacked the files to a location.

I was expecting the “configuration” tool to run, but it didn’t. It was not installed, and not an option.

I quickly read through the 5.7.1 changelog and found the config tool is not part of the .msi anymore. You must now use the “MySQL Installer” if you want to …

The MySQL team at Oracle are excited to announce the immediate availability of the MySQL Cluster 7.3 Development Milestone Release GA release. Some might call MySQL Cluster 7.3 "the foreign keys release" - and sure enough it is a major engineering achievement to build a distributed database that enforces referential integrity across a shared-nothing cluster, while maintaining ACID compliance and cross-shard JOINs. But MySQL Cluster 7.3 is so much more as well. The design focus has been on enabling developer agility - making it simpler and faster than ever to enhance new services with a highly scalable, fault tolerant, real-time database - with minimum development or operational effort.

More than once I have wished that mysqldump was never created. In many backup scenarios it is better to use other tools such as xtrabackup. However, there is still times when I end up using mysqldump. For one thing it is included with the mysql packages. It's "always there". Secondly, it sometimes is really a good fit for the tasks. And occassionally, with a bit of work, you can make it do neat tricks. 

I'm going to cover a few of the tricks I have used over the years. Hopefully you will find them helpful. In some cases one of these might even save your bacon.

Trick One:

One of the annoying issues with mysqldump is its lack of flexibility. It's very easy to dump all databases (--all-databases option), or one or more databases (--databases). Even dumping a single table isn't too difficult. But what about all the tables that start with "a"? You could specify each table on the command line, but I have ADD and I can't …

We have had some success with the introduction of Glimpsee last month. Merci !
I would like to thanks all of you who have registered and those who are interested in Glimpsee without even really knowing what’s going on.
It is really important for us to feel enthusiasm about our work, because we work hard to provide a tool that could improve your life.

We hope to offer a public beta release of Glimpsee before the end of the year and many more surprises before. Meanwhile, we would like to offer you an incomplete FAQ about Glimpsee, enjoy :
 

What is Glimpsee?

Glimpsee is a smart dashboard for lazy DBA (devops included) The dashboard provides, as Software-as-a-Service, a new way to view the status …

At Cloud Expo East 2013 I gave a presentation of my experiences in dealing with large AWS environments. In summary this included:

1. Understanding AWS Products (especially the growth of new/revised products and pricing)
2. Knowing the true Cost of your deployment and options with instances types, sizes and products
3. Being prepared for Web Scale
4. The importance of Security, what exists, the minimum you need to know working with external resources
5. Why most …

A few years back, along with some folks at MySQL and in the open source community, we helped kick off a campaign against software patents in Europe.  This was a hot topic and surprisingly, it seemed no large companies were willing to step up the fight.  As a relatively young company, MySQL had a lot to lose if someone went on the attack against us using patents.  While we had a very small number of patents in our portfolio (mostly through acquisitions), we help them only for defensive purposes.  

It's been interesting to see some stories come out from NPR's Planet Money and This American Life shows that shed more light on software patents.  The …
