MariaDB Foundation faces an unusual world, just like anyone else in these Corona times. Or perhaps, not quite. Here are some ideas for how to cope with a world inhibiting travel and social contact as we know it, from someone who has worked from home for 20 years, with colleagues also working from home.
First, stay upbeat. Humans are social animals, and we live off interactions with others. But Corona just dictates what type of social interactions we can have. It doesn’t inhibit social contact.
Second, stay connected.
The MariaDB Foundation is looking for a mid to senior-level C/C++ developer to work on MariaDB Server.
Our small team works remotely to build and support MariaDB, and requires strong skills in written English for daily communication.
A fulltime position is preferred.
We are looking in particular for people with an understanding of how open source works, how collaboration is fostered, how licenses and copyright work, and how tools such as git and test suites are best used. The person(s) should be a C/C++ developer by background, and ideally have a proven track record of producing code patches that have been accepted in major open source projects.
The MariaDB Foundation is pleased to announce the availability of MariaDB 10.5.1, the first beta release in the MariaDB 10.5 development series.
See the release notes and changelogs for details.

FOSDEM gives energy. FOSDEM gives ideas. FOSDEM opens up opportunities, FOSDEM allows you to connect with old friends and colleagues. Hence, no big surprise that MariaDB Foundation attended FOSDEM, in order to promote Open Source and to get ourselves closer to the community.
Starting from a pre-FOSDEM dinner with Member of the European Parliament Nils Torvalds, over Open Source Diva Danese Cooper’s keynote about “Open Source is Art”, to the MySQL, MariaDB and Friends Devroom and Sunday’s MariaDB Day, concluding with OpenForum Europe’s meeting on Monday, my previous weekend was packed with encounters, discussions, and ideas around Open Source.
Our first MariaDB Day in Brussels is seeing some interesting presentations. Slides and videos are posted below.
This post will be updated as more slides and presentations become available.
You can also view the live video stream.

Galera Cluster for MySQL is a 100% synchronized cluster in regards to data modification operations (DML). It is ensured by the optimistic locking model and ability to rollback a transaction, which cannot be applied on all nodes. However, schema changes (DDL operations) are not transactional in MySQL, which adds complexity when you need to perform an upgrade or change schema of the database.
Changes made by DDL may affect results of the queries. Therefore all modifications must replicate on all nodes prior next data access. For operations which run momentarily it can be easily achieved, but schema changes may take hours to apply.
Galera R&D team is currently finalizing new features targeted for the next MariaDB 10.5 release. This presentation is a high level overview of the most prominent Galera clustering features under work, such as:
* Non Blocking DDL – for less turbulence of schema upgrades in a cluster
* Cluster Error Voting – for immediate recovery of node failures
* XA transaction Support – for executing XA transactions in a multi-master cluster
* GTID consistency – for consistent GTIDs in hybrid cluster / replication topologies
* Black Box – cluster hardening through more detailed diagnostics
Application-time periods is another feature of SQL-2011. It’s main purpose is to introduce a per-table PERIOD entity, which generally is a pair of temporal fields: [period start, period end), and to set up a new set of syntax and constraints.
Note: the standard forbids these fields to be of type TIME, and to have more than one period per table.
The eminent part of application-time periods is a UNIQUE semantic extension — it adds a possibility to specify a period there, with adding WITHOUT OVERLAPS after it.
