“With MySQL 5.6, developers can now commingle the “best of both worlds” with fast key-value look up operations and complex SQL queries to meet user and application specific requirements” –Tomas Ulin. On February 5, 2013, Oracle announced the general availability of MySQL 5.6. I have interviewed Tomas Ulin, Vice President for the MySQL Engineering team [...]
Got open source cloud storage? Red Hat buys Gluster
+0 Vote Up -0Vote Down

Red Hat’s $136m acquisition of open source storage vendor Gluster marks Red Hat’s biggest buy since JBoss and starts the fourth quarter with a very intersting deal. The acquisition is definitely good for Red Hat since it bolsters its Cloud Forms IaaS and OpenShift PaaS technology and strategy with storage, which is often the starting point for enterprise and service provider cloud computing deployments. The acquisition also gives Red Hat another weapon in its fight against VMware, Microsoft and others, including OpenStack, of which Gluster is a member (more on that further down). The deal is also good for Gluster given the sizeable price Red Hat is paying for the provider of open source, software-based, scale-out storage for unstructured data and also as validation of both open source and software in

Binlog Group Commit Experiments It was a while ago since I talked about binary log group commit. I had to spend time on a few other things.

Since then, Kristian has released a version of binary log group commit that seems to work well.

Setting up Master-Slave Replication with MySQL
+1 Vote Up -1Vote Down
Replication enables data from one MySQL server to be replicated on one or more other MySQL servers. Replication is mostly used as scale-out solution. In such a solution, all writes and updates take place on the master server, while reads take place on one or more slaves. This model is actually known as master-slave replication and this is the kind of replication that I will be setting up in this post.
Continuent launches Tungsten project for database scale-out
+0 Vote Up -0Vote Down

Continuent is probably best known for its database clustering technology for MySQL, as well as PostgreSQL, but the company has for some time had its sights set on expanding beyond open source databases and enabling horizontal database scalability.

It has just taken a major step towards delivering on both counts with the launch of Tungsten, its new stack of open source middleware technologies designed to enable low-cost databases to scale horizontally for database failover and continuity.

Tungsten includes includes Sequoia, the existing synchronous

BLOB locators + BLOB streaming + Replication = Yeah!
Employee +0 Vote Up -0Vote Down
On the MySQL Conference & Expo 2007, I had the chance of meeting up with Paul (the author of PBXT) and Mikael. We briefly touched the topic of the BLOB Streaming Protocol that Paul is working on, which I find really neat. On the way back home, I traveled with Anders Karlsson (one of MySQL:s Sales Engineers), who is responsible for the BLOB Locator worklog and he described the concepts from his viewpoint.

Since I work with replication, these things got me thinking on what the impact is for replication and how it affects usability, efficiency, and scale-out. Being a RESTful guy, I started thinking about URIs both when
