The binary version for MySQL Cluster 7.1.13 has now been made available at http://www.mysql.com/downloads/cluster/

A description of all of the changes (fixes) that have gone into MySQL Cluster 7.1.13 (compared to 7.1.10) can be found in the official MySQL Cluster documentation for Cluster 7.1.13, 7.1.12 & 7.1.11.

Join us for a live webinar and download a new whitepaper where we discuss how to realize new value from data collected during web session management.

Session management has long been a key component of any web infrastructure – enhancing the user browsing experience through improved reliability, reduced latency and tighter security.

Increasingly organizations are looking to unlock more value from session management to further improve user loyalty (i.e. making the web service more “sticky”) and improve monetization of web services.  There are two distinct developments that offer the promise of unlocking more value from session data:
1.    Provide highly personalized browsing experiences by …

Henrik just wrote a good article on different ways of achieving high availability with MySQL. I was going to respond in the comments, but decided it is better not to post such a long comment there.

One of the questions I think is useful to ask is what kind of high availability is desired. It is quite possible for a group of several people to stand in a hallway and talk about high availability, all of them apparently discussing the same thing but really talking about very different things.

Henrik says “At MySQL/Sun we recommended against asynchronous replication as a HA solution so that was the end of it as far as MMM was concerned. Instead we recommended DRBD, shared disk or MySQL Cluster based solutions.” Notice that all of those are synchronous technologies (at least, the way MySQL recommended them to be configured), generally …

Severalnines will host a BOF at 7pm in Ballroom A, Tuesday 04/12.

After a succesful cluster tutorial we will demo how to use Severalnines Configurator to deploy MySQL Cluster on EC2 on X computers using one command (deploy.sh), complete with monitoring and management.

See you there!

The announcements at the Oracle Collaborate and O'Reilly MySQL conferences mark an exciting milestone in the development of the MySQL Cluster database.

MySQL Cluster is already proven as a write-scalable, real-time transactional database, combining 99.999% availability with the low TCO of open source. With a distributed, multi-master architecture and no single point of failure, MySQL Cluster scales horizontally on commodity hardware to serve read and write intensive workloads.

With these enhancements announced in the Development Milestone Release, MySQL Cluster can be extended to serve a broader range of workloads.

Summary of Key Enhancements

The MySQL Cluster 7.2 Development Milestone Release and latest labs.mysql.com builds deliver enhancements based on input from the community and customers, including support for the memcached NoSQL API, faster JOIN performance and simplified administration:

• …

The ever increasing performance demands of web-based services has generated significant interest in providing NoSQL access methods to MySQL - enabling users to maintain all of the advantages of their existing relational database infrastructure, while providing blazing fast performance for simple queries, using an API to complement regular SQL access to their data.

The HandlerSocket development at DeNA is a great example of community innovation, with a solution implemented as a custom plug-in and protocol for the MySQL server daemon.

We are hearing the community say they want NotOnly SQL - they want their trusted SQL RDBMS - plus, they want NoSQL techniques to access that data. So, we are previewing our NotOnlySQL solution for MySQL - delivered via memcached - with implementations to access both the InnoDB and MySQL Cluster (NDB) storage …
