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

Compatibility?
MariaDB Galera Cluster is fully data-compatible with MariaDB or MySQL, as it will work with the standard databases created by these products. There are next to none or very minimal application changes that are required to make the solution work.

Where can I get it?

What’s next?
The plan is for a rapid release cycle to heavily test the performance and usage of MariaDB Galera Cluster in different environments. Please file bugs at: https://mariadb.atlassian.net

“It’s great that we are working closely with an upstream provider of a MySQL-compatible binary, MariaDB. We no longer have to spend time coding against out-of-tree changes as we’re part of MariaDB,” stated Jaakola. “The excellent MariaDB engineering team constantly releases new versions of MariaDB with high quality assurance (QA). Codership will continue to collaborate closely with the MariaDB engineering team to improve the product and make new versions of the MariaDB Galera Cluster available.” he continued.

Michael “Monty” Widenius, CEO for Monty Program Ab
“We’ve received a significant amount of requests for a MariaDB based Galera cluster and today we’re proud to deliver that. We’re currently preparing ourselves and our partners for a rollout of the GA product and related professional services via SkySQL to run critical systems on top of MariaDB Galera Cluster.”

The MariaDB Team will together with Codership work on customer requests and demands in the areas of cluster and replication. Please contact us if you are interested in any services we can offer around Galera, MariaDB or MySQL.

A few months ago we announced the EXPLAIN Analyzer, a simple tool to help you understand how MariaDB / MySQL was running queries. For users of HeidiSQL this is now even easier. As discussed in their news post you can now send a query to the EXPLAIN analyzer with a single click.

We hope this helps both new and experienced users better understand the queries they run.

More information about the EXPLAIN Analyzer and the simple API client authors can use to add support to their apps is available in the AskMonty Knowledgebase:
