Introduction
Evaluating the performance of database systems is a very demanding task. There are a lot of hard choices to be made, e.g.:
- What operating system and operating system version is to be used
- What configuration setup is to be used
- What benchmarks are to be used and how long are the warm-up and measure times
- What test setups are to be used
- What version of the database management system is used
- What storage engine is used
While performance evaluation is mostly machine time, there is still a lot of hard work for the human monitoring the tests. …

Introduction
Eventual consistency [1] is a consistency model, which is used in many large distributed databases. Such databases require that all changes to a replicated piece of data eventually reach all affected replicas. Furthermore, the conflict resolution is not handled in these databases, and the responsibility is pushed up to the application authors in the event of conflicting updates. Eventual consistency is a specific form of weak consistency: the storage system guarantees that if no new updates are made to the object, eventually all accesses will return the last updated value [1]. If no failures occur, the maximum size of the inconsistency window can be determined based on the factors such as communication delays, the load on the system, and the number of replicas involved in the replication scheme. …

Today marks a milestone in terms of the MariaDB project – going forward, the MariaDB project plans to use Github and git for source code management. The migration happens from Launchpad and the bzr tool.
The 10.1 server development (under heavy development now) will happen on Github. You can check it out here: https://github.com/MariaDB/server. Feel free to watch, star or even fork the code, and send us contributions!
Previous maria-captains should now provide their Github IDs so that they can be accorded similar status. Send the IDs to the maria-developers mailing list. …
This is the blog of the MariaDB Foundation in particular and the MariaDB project in general. It is used to announce new MariaDB versions, for posts from MariaDB developers about new features, and for news from or about the MariaDB Foundation itself, among other things. For many this is the MariaDB blog, and on behalf of the MariaDB Foundation, welcome! We’re glad you’re here. Thanks for stopping by!
What you may not know is that there’s another MariaDB blog over at https://mariadb.com/blog run by the fine folks at SkySQL (full disclosure: I work for SkySQL, but my posts here are on behalf of the MariaDB project and the Foundation). …
In January I wrote my first post about node.js and MariaDB . In February I continued with a second post about using jQuery and some GIS calculations. Now it is time for the third and this time the main focus is not so much on GIS functionality, but instead on the capabilities MariaDB has for handling piles of unstructured data. In this case I’ll be focusing on crunching a pile of XML files without importing the XML data itself.
MariaDB 10.0, which had its GA launch in early April, includes the Connect engine. …
Dotdeb is a repository currently targeting Debian and Ubuntu, providing a nice set of packages for LAMP servers.
Recently, MySQL 5.6 was added to the dotdeb repository. On the surface, this is a very harmless addition. MariaDB is a replacement for MySQL and it should be possible for applications designed for MySQL to easily switch to MariaDB. Therefore MariaDB also includes the libraries that applications using MySQL depend upon, such as libmysqlclient18 and mysql-common. The dpkg package manager looks at the MySQL 5.6 packages in dotdeb and assumes that 5.6 is a higher version than 5.5, which results in it removing or replacing libraries during normal apt-get installation and upgrade procedures. …
