FOSDEM 2020: Some memories and todos

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.

FOSDEM logo

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.

MariaDB Day Brussels 02.02.2020 – Introducing speakers – Sveta Smirnova on How to Avoid Pitfalls in Schema Upgrade with Galera

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.

MariaDB Day Brussels 02.02.2020 – Introducing speakers – Seppo Jaakola on MariaDB 10.5 new Galera features

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

MariaDB Day Brussels 02.02.2020 – Introducing speakers – Nikita Malyavin on 5 Application-time periods in MariaDB – new syntax and table constraints: from PORTIONs to FOREIGN KEYs

We continue presenting our MariaDB Day Speakers. Please remember to register for the event at the Meetup page.

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.

MariaDB day Brussels 02.02.2020 – Introducing speakers – Vicențiu Ciorbaru on comparing MariaDB and MySQL Roles.

MySQL 8.0 has introduced roles, a feature that was present since MariaDB 10.0. There are quite a number of differences between the two databases.

During the MariaDB day Vicențiu will present a comparison between them and see how roles are useful for your application and what are the key differences to consider when working with both databases.
