The MariaDB Server Fest next month has approved quite a number of exciting presentations. The presenters are now busy filming their presentations, which will be aired three times – Monday to Wednesday 14-16 September 2020 in the Paris timezone (for EMEA), Tuesday to Thursday 15-17 September 2020 in the New York timezone (for the Americas), and Friday to Sunday 18-20 September 2020 in the Beijing timezone (for APAC).
Interactivity through cloning
Through logic (not magic), we have cloned the presenters. As the presentation is aired in the form of video, slides and voice, the presenter is fully concentrating on following what you, the attendee, ask in the chat room.
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).
Thank you for the many submissions to our Call for Papers, and to your insightful replies to our Call for Attendees.
Based on the CfA replies and other feedback given to us, we could draw a few conclusions.
Attendees: Three-day event
First, we will spread out the event from a two-day event to a three-day event, for the attendees. We received several comments around preferences for shorter days, giving time for “normal” work. Rather three short days, than two long ones. That made perfect sense to us. We already changed a couple of convetions when moving from a physical event to a virtual;
On Wednesday 24 June 2020, MariaDB Server 10.5 was released GA. While there are several cool new features included, this first 10.5 blog is about the groundbreaking new component, ColumnStore.
The big picture
ColumnStore brings data warehousing to the world of MariaDB Server. It’s a columnar storage engine (Wikipedia: Column-oriented DBMS), enabling what is often called HTAP (Wikipedia: Hybrid Transactional/Analytical Processing). The Columnar data type stores data by columns, not by rows, enabling quick analytical reporting over huge data volumes.
The news
The ColumnStore engine is part of MariaDB Server 10.5.
Join our Online Conference in September! In three different time zones, we will meet users of MariaDB Server for two packed days of presentations, interactions and insights.
The Call for Papers is open. And we have a favour to ask everyone considering attending: Please fill in our Call for Attendance survey! We need your help to ensure that we do logistics right when it comes to timing and formats, that we cover all topics that interest you, and that we prepare interactivity and tools in the best possible way.
How do you select a database in practice? How do you pretend to select it? And, if you want to be serious, how do you select it logically?
Those are the key questions I dug into, during my keynote last week at Percona Live Online.
For those who feel they don’t want to listen to the entire 30 minute video of the presentation, I have compiled a number of entry points for you below:
It certainly doesn’t feel like 25 years ago that Monty released MySQL. At that time, I thought it was a bit redundant of Monty to create Yet Another Database, the world was full of them already. But MySQL turned out to become the database for Internet, growing hand-in-hand with PHP (and Perl and Python).
When MySQL was created 1995, Monty’s oldest daughter My was six years old. When the first MariaDB was released 2009, My’s little sister Maria was one year younger, five years old.
The oldest mysql.com site I found: 5 July 1998
One innovation over the other databases was the license model.
Planet MariaDB has been reworked from scratch, getting a new instance with the same look and feel as the rest of mariadb.org.
Three news items, related to that: One bad, one neutral, one good. I’m saving the good one for last, as I hope you will like it.
Bad news: The old Planet had five different RSS feeds, we now have only one. We maintain the format changes only on one RSS feed, which means that some of you will have to update your RSS feed to https://mariadb.org/planet-feed.xml (also listed on Planet MariaDB). That said, we are working on further redirects;
