The MySQL Cluster product team is always interested to see new and innovative uses of the database. Last week, a team of students at the KTH Royal Institute of Technology in Sweden blogged about their use of MySQL Cluster in creating a scalable and highly available HDFS Namenode. The blog has received some pretty wide coverage, but was first picked up by Alex Popescu at the myNoSQL site

There are many established use cases of MySQL Cluster in the web, cloud/SaaS, telecoms and even flight control systems – you can see those we are allowed to talk about publicly …

By taking this newly updated course,  MySQL for Database Administrators,
students will benefit from learning how to secure users privileges, set resource limitations, access controls, describe backup and recovery basics and more... There is never a better time to get the training you need - end the year by gaining some new skills!

From simple to full featured cloud capacity

Cloud technologies and services increase every day. Global players like Amazon put continuously new features to their cloud and products to provide sufficiently functionality of actually web development activities and requirements.

Services for us

In fact, Amazon starts with the S3 (Simple Storages Service) to provide cloud storage space since 2006 and only a few months later EC2 (Elastic Compute Cloud) was launched a service to provide computing power to manage capacity as many as we need over time. Now, RDS (Relational Database Service) is available to get elastic database power as much as we need to cover all components that we require to implement the whole stack of current web applications.

Galera release 1.1 has been published and rolled out in the open!

This release has a bunch of bug fixes and one prominent new feature: rolling schema upgrade. With rolling schema upgrade, it is possible to apply schema changes (DDL statements e.g. CREATE, DROP, ALTER, etc...) for each cluster node separately. The node to be upgraded is a member of cluster but is not applying replication events as long as the DDL statement is processing. With this, the cluster can stay in production due out the schema upgrade process. I will write a more detailed description how it works in a separate blog.

The 1.1 release uses new version of replication API: wsrep API #22. This means that both MySQL and Galera components must be upgraded with same go.

Galera release 1.1 is available for downloads: …
