MariaDB Galera Cluster Alpha immediately available

Today we’re pleased to announce the availability of MariaDB Galera Cluster!

With this release, we’re addressing the numerous requests we’ve received over the past few months for a MariaDB-based Galera Cluster. MariaDB, the more reliable, performant, feature-complete & backwards compatible MySQL database becomes even more attractive by making it available for Galera Cluster.

What is it?

  • A straight merge of MariaDB 5.5.25 with Galera Cluster by Codership
  • An alpha release which should not be used in production environments
  • Using the Galera replication methodology, users get:
    • Synchronous, multi-master replication with guaranteed data consistency
    • This solution provides both read & write scalability

Webinar: Understanding Indexing

Three rules on making indexes around queries to provide good performance

Application performance often depends on how fast a query can respond and query performance almost always depends on good indexing. So one of the quickest and least expensive ways to increase application performance is to optimize the indexes. This talk presents three simple and effective rules on how to construct indexes around queries that result in good performance.

Time: 2PM EDT / 11AM PDT

This webinar is a general discussion applicable to all databases using indexes and is not specific to any particular MySQL® storage engine (e.g., InnoDB, TokuDB®, etc.). The rules are explained using a simple model that does NOT rely on understanding B-trees, Fractal Tree® indexing, …

Consolidating MariaDB project tools

It is not a secret that we’ve been kicking the tires and playing with JIRA for project management. After using it since the beginning of the year most of us like the feel of it and we’ve decided that it makes sense to start using it more.

As you know, the MariaDB project has many fragmented resources. We report bugs in Launchpad. We store our plans in worklog. We’ve never used the Launchpad Blueprint feature for this very reason. We don’t use Launchpad Answers because we have the Knowledgebase.

With this move to hosted JIRA (yes, this is an important link: …

Monty Program & SkySQL: a statement on the serious security vulnerability that was found in MariaDB and MySQL

Over the past few days extensive conversations around a new security vulnerability in MariaDB and MySQL have taken place.

It all started as a chain reaction when Monty Program publicly disclosed information about the flaw they had found and about how to make sure your MariaDB and MySQL installations can be fixed. The initial information got assigned the security vulnerabitlity identifier CVE-2012-2122 and the contents can be seen e.g. here

The bug was found two months ago on April 4th.

Before disclosing the information publicly, given the seriousness of this bug and considering the millions of MySQL and MariaDB installations deployed worldwide, Monty Program informed the biggest distributors of MySQL and MariaDB as a precaution.

On April 6th, Monty Program informed Oracle about it in bug report …

Webinar: TokuDB v6 Replication Performance

TokuDB® is a proven solution that scales MySQL® and MariaDB® from GBs to TBs with unmatched insert and query speed, compression, and online schema flexibility.

Tokutek’s recently launched TokuDB v6 delivers all of these features and more, with the introduction of high performance replication for MySQL and MariaDB. TokuDB v6 eliminates the common and persistent problem of “slave lag” in which a replication server is unable to keep up with the query load borne by the master server. TokuDB v6 solves this by offering high ingestion rates at the slave.

Time: 2PM EDT / 11AM PDT

What comes in between MariaDB now and MySQL 5.6?

We’re quite happy that we’ve released four major releases that are production ready (better known as generally available or GA in the MySQL world) in the last 26 months. That is just a little over two years, and a whole lot of features. In that same time, MySQL has seen one GA release (MySQL 5.5) and we’re all eagerly awaiting the upcoming MySQL 5.6.

You’ll note that we built MariaDB 5.1, 5.2, and 5.3 based on the MySQL 5.1 codebase. A significant number of features went into MariaDB 5.3 (our biggest GA release to date), with the biggest changes in the optimizer in over a decade. There were also many replication based …

Challenges of Big Databases with MySQL – IOUG Presentation



Many database management tasks become difficult as you move from millions of rows and gigabytes of data to billions of rows and terabytes of data. Such tasks include ingesting data while maintaining indexes; changing schemas without downtime; and supporting connections, replication, and backup. For some scaling problems (connections and replication), MySQL® is better than most of the competition. For others, such as indexing, schema changes, and backup, MySQL has typically been harder to use. Fortunately, the tasks MySQL does well are in its core, whereas the tasks that are more difficult can be solved with storage engine plug-ins.

I recently gave a talk at IOUG Collaborate, a copy of which can be found here. This …
