In many environments MySQL is not the only technology used to store in-process data.

Quite frequently, especially with large-scale or complicated applications, we use MySQL alongside other technologies for certain tasks of reporting, caching as well as main data-store for portions of application.

What technologies for data storage and processing do you use alongside MySQL in your environment? Please feel free to elaborate in the comments about your use case and experiences!

“Application designers need to start by thinking about what level of data integrity they need, rather than what they want, and then design their technology stack around that reality. Everyone would like a database that guarantees perfect availability, perfect consistency, instantaneous response times, and infinite throughput, but it´s not possible to create a product with [...]

Together with Sergei Petrunia, we talked about MariaDB Cassandra Interoperability. Sergei has done wonderful work here and I plan to showcase more Cassandra integration going forward. It’s worth noting that Elena came up with the benchmarks for this talk as well.

Extract from THE SCALE-OUT BLOG by Robert Hodges (CEO, Continuent)http://scale-out-blog.blogspot.com Data management is undergoing a revolution. Many businesses now depend on data sets that vastly exceed the capacity of DBMS servers. Applications operate 24x7 in complex cloud environments using small and relatively unreliable VMs. Managers need to act on new information from those systems in

FOSDEM 13 is now over, I am on my way home and I would like to share some thoughts sparkled by the intense atmosphere that I have lived in these two days in Brussels.

I have to admit, I was tempted to skip FOSDEM this year: the last 3 weeks have been crazily busy and I travelled a lot, leaving my family alone for too long. But now I am glad I made the effort.
For once, I will leave the comments around the MySQL talks to others, I am sure there will be posts on the matter. In this post I want to cover some of the non-MySQL talks and discussions I have attended and heard. Of course the topics that have been discussed are still relevant for MySQL and for the future of the MySQL ecosystem.
First of all, the number of attendees was impressive. The organisers claim there were more than 5,000 open source enthusiasts, in my opinion the number was even higher. Every room was …

The Apache Software Foundation Announces Apache Cassandra v1.2 bit.ly/UFGKFN

— Matt Aslett (@maslett) January …

We’re pleased to announce the first preview version of the Cassandra Storage Engine!

The Cassandra Storage Engine (SE) allows access to Cassandra databases from MariaDB/MySQL, and to provide data integration between the SQL and NoSQL worlds.

Have you ever needed to

• grab some of Cassandra’s data from your web frontend, or SQL query?
• insert a few records into Cassandra from some part of your app?

With Cassandra SE, this is easily possible. Cassandra SE makes Cassandra’s column families appear as MariaDB/MySQL tables that you can insert to, update, and select from. You can perform joins on Cassandra data, or againist data in Cassandra and data in MariaDB.

Today we’re releasing a source tarball, as well as a binary tarball package …

Infor announced this week, that they will provide open source database alternatives to some of their products. MariaDB has been chosen, tested, and certified by Infor to be the open source database of choice (together with MySQL) for the Infor LN and ION products. Infor LN is Infor’s flagship ERP and is sometimes better known by its former name, Baan. It has 25 years of manufacturing know-how built into it and is used by more than 5,000 companies worldwide in a wide range of industries. These include automotive, industrial equipment and machinery, high tech and electronics, and aerospace and defense. This is a big stamp of approval that even the most critical systems can be run on MariaDB.

In other news, there are currently several really interesting paths coming together into some important milestones. The rest of this post …

What is Ansible?

Ansible is a configuration management and deployment system, like Puppet, Capistrano, Fabric, and Chef. Its aim is to be radically simple and let you use your existing scripts to help with cluster configuration and software deployment whenever possible. Here are the ways that Ansible differentiates itself.

Simplicity

Ansible does not include a client/server architecture with pull-based clients (although in more recent versions, it does include pull-based configuration and deployment). Rather, it uses pre-existing network infrastructure: SSH. Every company has SSH installed on their cluster servers, and Ansible simply rides on top of this infrastructure to get the code and configuration out to the nodes.

Language Agnostic

You can write modules for Ansible in …
