We are proud to announce the beta release series of the MariaDB Jupyter Kernel, making MariaDB Server accessible through the popular next-generation web-based interface.
For all who love the easy Jupyter user interface, there is now a way to access the MariaDB Server from everyone’s favorite notebook.
The MariaDB Jupyter Kernel is as simple as it gets. It’s a “normal” MariaDB character based command line client, extended in two ways: First, it has all the standard Jupyter usability functionality for editing and saving MariaDB SELECT, INSERT, UPDATE and DELETE commands.
Machine learning is one area that cannot succeed without data. Traditionally, machine learning frameworks read it from CSV files or similar data sources. This brings an interesting set of challenges because in most cases the data is stored in databases, not simple raw files. It takes time and effort to move data from one format to another. Additionally, one needs to write some code (usually python) to prepare the data just like the ML framework expects it.
My primary motivation to contribute to the open source community is because I strongly believe in the idea that software is free, to copy, modify and study.
Our very own Ian Gilfillan has created a brief and clear video called Get Set for Set Theory: UNION, INTERSECT and EXCEPT in SQL
In a tad more than six minutes, you’ll see exactly how UNION, INTERSECT and EXCEPT work, starting in MariaDB 10.3, a few years back.
Ian explains what they are for, and the option to change default behaviour of DISTINCT with ALL (of which the ALL option was introduced in MariaDB 10.5).
That’s not new.
MariaDB deployments hold vast amounts of sensitive data such as intellectual property, state secrets, healthcare and financial records. HIPAA, GDPR and other government regulations require even more stringent protections and disclosures. Achieving post-compromise protection is seen as a necessary new tool available to DevOps teams.
At the first MariaDB Day in Brussels on February 2nd, Virgil Security’s CTO and co-founder Dmitry Dain presented a MariaDB demo based on the Virgil PureKit security framework that can protect stored passwords, PII and any other sensitive data even if the database had been breached – making it worthless to the attacker in the face of offline attacks (read more about security benefits in this blog post).

MariaDB Foundation is commited to ensuring MariaDB Server has a thriving community of developers and contributors. A software project cannot be maintained without proper tests. mysql-test-run is our standard testing toolkit for MariaDB Server. What it (mostly) does is run queries against one or more servers and compare their output to the expected one. This checks both behaviour and data consistency. The main principle is the server should always return the same data that is put into it.
One problem with this testing method is that it only covers the hosts’ environment. That means that if you are running Debian on x86_64 architecture, you are testing x86_64 architecture on a Debian Linux distribution. Read more
