Announcing ClusterControl Support for MariaDB 10
+0 Vote Up -0Vote Down
July 22, 2014 By Severalnines

We just wanted to make it official: Severalnines ClusterControl now supports MariaDB 10!

 

As most of you know will know by now, MariaDB 10 is the newest and most advanced version of the popular MariaDB relational database system. Whilst remaining application-compatible with the MySQL database, it adds many new capabilities to address the most challenging web and enterprise application use cases. Cluster deployments would be based on MariaDB Galera Cluster 10, which is a complete merge of MariaDB 10.0.12 and Galera Cluster.

Installing MariaDB Galera Cluster on Debian/Ubuntu
+1 Vote Up -0Vote Down

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

In our setup we assume 3 nodes (node01, node02, node03) with one interface each. We assume following IP addresses: 172.16.8.5, 172.16.8.6, and 172.16.8.4. We need three packages installed on all nodes:

  • rsync
  • galera
  • mariadb-galera-server

Auto increments in Galera
+0 Vote Up -0Vote Down

Lets start by considering a scenario where records are being inserted in a single auto-increment table via different nodes of a multi-master cluster. One issue that might arise is ‘collision’ of generated auto-increment values on different nodes, which is precisely the subject of this article.

As the cluster is multi-master, it allows writes on all master nodes. As a result of which a table might get same auto-incremented values on different nodes on INSERTs. This issue is discovered only after the writeset is replicated and that’s a problem!

Galera cluster suffers with the similar problem.

Lets try to emulate this on a 2-node Galera cluster :

1) On node #1:

MariaDB [test]> CREATE TABLE t1(c1 INT AUTO_INCREMENT PRIMARY KEY, c2 INT)ENGINE=InnoDB;
Query OK, 0 rows affected (0.07 sec)

MariaDB [test]> START TRANSACTION;
Query OK, 0
