At this week’s re:Invent conference, Amazon Web Services (AWS) announced it is joining the MariaDB community with the introduction of its Relational Database Service (RDS) for MariaDB. Amazon’s decision was driven by the growing demand among its customers for MariaDB, which now has over two million users in 45 countries.


Parallel replication is a much-expected feature of MySQL. It is available in MariaDB 10.0 and in MySQL 5.7. In this 3rd post of the series, we present benchmark results from production environments.

The Convergence of Enterprise-Class and Choice – an Open Source Ecosystem Running on a True Enterprise-Class Platform: MariaDB Enterprise on IBM z Systems

While selling free software sounds like a hard job, the growing mainstream adoption of open source makes it one of the most exciting segments in IT. In my daily meetings with customers, there is no ambiguity that open source is the foundation for the hottest trends in technology, including Cloud, Analytics, Mobile and Social. Gartner reports that 70% of all new applications are built using an open source database. (1)

Conservative in-order parallel replication is a great feature in MariaDB 10.0 that improves replication performance by using knowledge of group commit on the master to commit transactions in parallel on a slave. If slave_parallel_threads is greater than 0, then the SQL thread will instruct multiple worker threads to concurrently apply transactions that were committed in the same group commit on the master.

MariaDB and Foedus paths crossed less than a year ago when I met Paolo Messina at a two-day IBM event in Tuscany. IBM invited me, as the MariaDB Italian representative, to introduce MariaDB as an Open Source Solution for the POWER8 platform.

MaxScale 1.2.0 and above can call external scripts on monitor events. In the case of a classic Master-Slave setup, this can be used for automatic failover and promotion using MariaDB Replication Manager. The following use case is exposed using three MariaDB servers (one master, two slaves) and a MaxScale server.

Parallel Replication is a fantastic addition to the long list of new MariaDB 10.0 features. In his blog post, Remote DBA Guillaume Lefranc explains how to leverage parallel replication's potential.

In the last two releases of MariaDB Enterprise, we have provided enhanced performance with the introduction of certified MariaDB binaries for POWER8 and optimized binaries for the x86 platform. This Summer we make it more efficient and automated for developers and DBAs to use our high performance MariaDB binaries.

It was a very long time since I wrote something in this blob, but I have been very busy this spring with MariaDB on Power. This has been a lot of work, but also a lot of fun. So, what is this MariaDB on Power thing all about, well I wrote an introduction to the Power platform late last year. Since then a lot of things has happened.

Setting up data security correctly can be vital for systems at government agencies, e-commerce sites, hospitals and clinics, or any company with sensitive employee data. In this blog, Geoff shows you how to set up row-level security in MariaDB for use cases demanding more detailed privilege handling than MariaDB and MySQL provide out of the box.
