Performance evaluation of MariaDB 10.1 and MySQL 5.7.4-labs-tplc
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

Eventually Consistent Databases: State of the Art
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 […]

MariaDB Eventually Consistent?
Background
Eventual consistency is a consistency model used in many large distributed databases which requires that all changes to a replicated piece of data eventually reach all affected replicas; conflict resolution is not handled and responsibility is pushed up to the application author in the event of conflicting updates [13].
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 […]

Installing MariaDB Galera Cluster on Debian/Ubuntu
A MariaDB Howto authored by: Erkan Yanar.
This is a Howto about installing MariaDB Galera Cluster on Debian/Ubuntu. Because a lot of people were having problems installing MariaDB Galera Cluster, elenst from #maria on freenode forced me to write this Howto 🙂
Installing MariaDB Galera Cluster is in fact quite easy and actually kind of boring in the end. This Howto is written for (and tested on) on Debian 7.1 (Wheezy) and Ubuntu 12.04 (Precise).
What we need
