MariaDB OpenWorks happened February 25-27 2019 in New York City, and it was filled with a lot of activity.
The keynote by Michael Howard is an interesting watch, one with many quoted articles especially around “strip-mining open source technologies and companies,” and “abusing the license and privilege, and not giving back to the community.” Many articles were written about this topic, and it is clear that open source has arrived considering all the success around the IBM acquisition of Red Hat, the Elastic IPO, the Microsoft acquisition of GitHub, the SalesForce acquisition fo MuleSoft and the MongoDB IPO.
Seppo Jaakola talked about What’s new in Galera 4. Expect a lot more blogs about this, and don’t forget to read Galera Cluster 4 available for use in the latest MariaDB 10.4.3 Release Candidate!.
From a Galera Cluster standpoint, it would be recommended not just to watch the video: Auto Europe’s ongoing journey with MariaDB and open source but to also read an excellent article by Jon Reed on Diginomica: OpenWorks 2019 – why Auto Europe moved their CMS database to open source, and what they’ve learned.
Auto Europe has a three node Galera Cluster running their MariaDB installation. One of those nodes is in a separate data center from the other two, so even if an entire data center goes down, Auto Europe is still up.
It only took two days of consulting to get them up to speed!
Nokia Networks Rick Lane is also a happy user of Galera Cluster, as you can see in the video Deploying MariaDB databases with containers at Nokia Networks. At about 14 minutes in, you will note that their MariaDB container supports deployment of all configurations including Galera Cluster. At 35:40, he goes into Galera Cluster healing and the challenges they faced getting this going. There is also Galera Cluster scaling shortly thereafter (scale out, and “scaling in”, i.e. shrinking the cluster size, but no less than 3 nodes).
CCV is a Dutch payment processor and loyalty processor, and their video CCV: migrating our payment processing system to MariaDB is a great watch too as they migrated from SQL Server 2008, have 2 data centres, use 5 Galera Cluster nodes per data centre, and the best quote: “MariaDB together with Galera [Cluster] is a really good fit for disaster recovery and near zero downtime. You can roll a data change right through the Galera Cluster starting on the first node and to the fifth node, and that fits us well.”
There were many people coming to the Galera Cluster booth at the Expo Hall, and overall, we are looking forward to MariaDB OpenWorks 2020!
