I stopped working on MySQL at Sun Microsystems in late 2009 (after a lengthy period of garden leave), to join Monty Program Ab, and was greatly anticipating a MariaDB release that we could take to market. The first GA release of MariaDB came out February 1 2010 – MariaDB 5.1.42. Today is MariaDB Server’s 5th birthday!

We didn’t even want to call it GA back then — we referred to it as a “stable” release. We didn’t make our own builds because we figured source code tarballs were good enough; so builds were made and hosted at OurDelta. It took some months (around August 2010) when we moved release notes to the Knowledgebase (which you’ll notice has moved from kb.askmonty.org to its current location) from the old front page wiki …

Following on the heels of last week’s update to the Java client, the MariaDB project is pleased to today announce updates to both MariaDB Connector/C and Connector/ODBC. They are both Stable (GA) releases.

See the Release Notes and Changelogs for detailed information on each of these releases and contain many bug fixes and enhancements.

Madrid MySQL Users Group will have its next meeting on Thursday, the 29th of January. I will be giving a presentation on the MySQL binlog server and how it can be used to help scale reads and be used for other purposes.  If you have (more than) a few slaves this talk might be interesting … Continue reading MMUG11: Talk about binlog servers at Madrid MySQL Users Group meeting on 29th January 2015

Unlike standard MySQL server and MySQL Cluster, the way to start a MySQL/MariaDB Galera Cluster is a bit different. Galera requires you to start a node in a cluster as a reference point, before the remaining nodes are able to join and form the cluster. This process is known as cluster bootstrap. Bootstrapping is an initial step to introduce a database node as primary component, before others see it as a reference point to sync up data.

How does it work?

When Galera starts with the bootstrap command on a node, that particular node will reach Primary state (check the value of wsrep_cluster_status). The remaining nodes will just require a normal start command and they will automatically look for existing Primary Component (PC) in the cluster and join to form a cluster. Data synchronization then happens through either incremental state transfer (IST) or …

Apache CloudStack is a turnkey orchestration platform to deliver IaaS clouds. As a cloud infrastructure scales to hundreds or thousands of servers, with production environments supporting multiple applications and services, high availability becomes a key requirement. Just as for OpenStack, it is possible to deploy the CloudStack management server in a multi-node installation. Since the management server uses a MySQL database to store the state of all its objects, the database could become a single point of failure. The CloudStack manual recommends MySQL replication with manual failover in the event of database loss. We believe there is a better way.

In this blog post, we’ll show you how to deploy redundant CloudStack management servers with …

MariaDB 10.1.2 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.1.2/

This is the third alpha release of MariaDB 10.1, so there are still a lot of new changes, functionalities added, defaults changed, and many bugs fixed (I counted 117, which is *way* down from the 637 fixed in 10.1.1). Since it’s alpha, I’ll only cover the major changes and additions, and omit covering general bug fixes (feel free to browse them all here).

To me, these are the highlights of the new features:

• –mysql56-temporal-format option to use the MySQL-5.6 low level formats to store …

MariaDB 10.0.15 was recently released, and is available for download here:

https://downloads.mariadb.org/mariadb/10.0.15/

This is the sixth GA release of MariaDB 10.0, and 16th overall release of MariaDB 10.0.

This release has an important InnoDB/XtraDB fix, a new addition, security enhancements (and improvement) – all related to yaSSL, so be sure to check out these fixes if you’re running MariaDB 10.0, and not up to 10.0.15 yet. (MariaDB 10.0 is the current stable series of MariaDB. It is an evolution of the MariaDB 5.5 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6.)

Here are the main items of note:

1. This release fixes a serious bug in InnoDB and XtraDB that sometimes could cause a hard lock up of the server ( …
