For a large Open Source project to survive, it needs the right testing infrastructure in place. Because of this, the MariaDB Foundation made the whole build system a community shared resource. In this talk we will show how we have accomplished this and how the community can benefit.
MariaDB has an Open Source engine called ColumnStore which provides columnar storage capabilities. During the MariaDB Day Andrew Hutchings (a.k.a. LinuxJedi) will hold a talk explaining what columnar storage is, how it works and the advantages / disadvantages of it. He will also talk about how you can use it to help with things such as your analytical workloads alongside your traditional OLTP workloads.
