- Texas LinuxFest – July 8-9 2016 – Austin, Texas – I’ve never spoken at this event before but have heard great things about it. I’ve got a morning talk about what’s in MariaDB Server 10.1, and what’s coming in 10.2.
- db tech showcase – July 13-15 2016 – Tokyo, Japan – I’ve regularly spoken at this event and its a case of a 100% pure database conference, with a very captive audience. I’ll be talking about the lessons one can learn from other people’s database failures (this is the kind of talk that keeps on changing and getting better as the software improves).
- The MariaDB Tokyo Meetup – July 21 2016 – Tokyo, Japan – Not the traditional meetup timing, since its 1.30pm-7pm, there will be many talks and its organised by the folk behind the SPIDER storage engine. It should be fun to see many people and food is being provided too. In Japanese: MariaDB コミュニティイベント in Tokyo, MariaDB Community Event in TOKYO.

We had the first MariaDB Berlin Meetup on Tuesday 12.04.2016 at the Wikimedia Berlin offices at 7pm. More or less there were over 54 people that attended the event, a mix of MariaDB Corporation employees and community members. We competed with the entertainment at the AWS Summit Berlin which was apparently about 400m away! Food and drink were enjoyed by all, and most importantly there were many, many lightning talks (minimum 5 minutes, maximum 10 minutes – most were about 6-7 minutes long).
The bonus of all of this? Lots and lots of slides for you to see. Grab them from the Google Drive folder MariaDB Berlin meetup April 2016.
- Monty talked about improving the speed of connections to MariaDB Server, some work he’s just pushed fairly recently to the 10.2 tree.
- Dipti spoke about MariaDB ColumnStore and it is now clear we’ll see some source/binary drop by the end of May 2016.
- Sergei Petrunia and Vicentiu Ciorbaru spoke about the upcoming window functions that MariaDB Server 10.2.0 will see (yes, the alpha should be out real soon now).
- Jan spoke about InnoDB in 10.2.
- Lixun Peng spoke about a fairly interesting feature, the idea to flashback via
mysqlbinlogand how you can have a “Time Machine”. I can’t wait for flashback/time machine to appear in 10.2. The demo for this is extremely good.
- Kolbe spoke about data at rest encryption using the MariaDB Amazon AWS KMS plugin.
- Sanja and Georg went up together to speak about 10.2 protocol enhancements as well as what you’ll see in Connector/C 3.0.
- Wlad gave us a good rundown on authenticating with GSSAPI, something you will notice is also available in MariaDB Server 10.1’s later releases.
- Johan Wikman gave us an introduction to MariaDB MaxScale, which started off the talks on MaxScale.
- Markus talked about the readwritesplit plugin.
- Massimiliano went into the Binlog server.
- Martin didn’t use slides but gave us an amazing talk titled “Rival concepts of SQL Proxy”; it was very well given and I’ve encouraged him to write a blog post about it.
- Community member Ben Kochie, an SRE at SoundCloud gave us a quick talk on Monitoring MySQL with Prometheus and how much they depend on the PERFORMANCE_SCHEMA.
- Diego Dupin spoke a little about the MariaDB Java Connector, and the idea was to do a demo but the projector via HDMI seemed to be a bit wonky (this was also true of using my Mac; the VGA output however worked fine). So it was just a quick talk without any deck.
We ended with a quick Q&A session with Monty dominating it. Lots of interesting questions around why the name Maria, licensing thoughts, ensuring all the software we have are in distributions, etc. Some ended up going for pizza while others ended up in a hotel bar at the Crowne Plaza Potsdamer Platz — and the chatter went on till at least 11pm.
Thanks again to Georg Richter who found us the venue and also did a lot of the legwork with Wikimedia Foundation.
The problem with Twitter is that we talk about something and before you know it, people forget. (e.g. does WebScaleSQL have an async client library?) How many blog posts are there about Percona Live Santa Clara 2015? This time (2016), I’m going to endeavour to write more than to just tweet – I want to remember this stuff, and search archives (and also note the changes that happen in this ecosystem). And maybe you do too as well. So look forward to more blogs from Percona Live Data Performance Conference 2016. In the meantime, here’s tweets in chronological order from my Twitter search.

There are a few upcoming speaking gigs this March 2016:
Two talks in London and one keynote in Singapore, while I will also moderate the database track on the last day of the conference as well. I’ve never been to flossUK before, but the schedule looks very interesting and I’m looking forward to it. FOSSASIA is an event I’ve been going to regularly since it was held in varying places (Vietnam, Cambodia, before finally settling down in Singapore) so this is an always exciting time.
Would happily meet you to talk shop, feel free to drop me an email: colin[at]mariadb.com.
I think one of the big announcements that came out from the Amazon Web Services world in October 2015 was the fact that you could spin up instances of MariaDB Server on it. You would get MariaDB Server 10.0.17. As of this writing, you are still getting that (the MySQL shipping then was 5.6.23, and today you can create a 5.6.27 instance, but there were no .24/.25/.26 releases). I’m hoping that there’s active work going on to make MariaDB Server 10.1 available ASAP on the platform.
Just last week you would have noticed that Amazon has rolled out MySQL 5.7.10. The in-place upgrades are not available yet, so updating is via dump/reload or using read replicas. According to the forums, a lot of people have been wanting to use the JSON functionality.
Are you trying MySQL 5.7 on RDS? How about your usage of MariaDB Server 10.0 on RDS? I’d be interested in feedback either as a comment here, or via email.
SCALE14x was held at Pasadena, Los Angeles this year from January 21-24 2016. I think its important to note that the venue changed from the Hilton LAX — this is a much bigger space, as the event is much bigger, and you’ll also notice that the expo hall has grown tremendously.
I had a talk in the MySQL track, and that was just one of over 180 talks. There were over 3,600 people attending, and it showed by the number of people coming by the MariaDB Corporation booth. I spent sometime there with Rod Allen, Max Mether, and Kurt Pastore, and the qualified leads we received were pretty high. Of course it didn’t hurt that we were also giving away a Sphero BB-8 Droid.
The MySQL track room was generally always full. We learned some interesting tidbits like Percona Server 5.7 would be GA in February 2016 (true!), the strong crowd at the MariaDB booth and quite a bit more. People are definitely interested in MySQL 5.7’s JSON functionality.
The highlight of my talk, The MySQL Server Ecosystem in 2016 was that it brought along quite a good discussion on Twitter. Its clear people are very interested in this and there is much opportunity for writing about this!
The Mark Shuttleworth keynote
But there were other SCALE14x highlights, like the keynote by Mark Shuttleworth. It was generally a very moving keynote, and here are a few bits that I took as notes:
- Technology changes lives
- Society evolves because it becomes possible to live differently
- New software moves too fast for distributions (6 months is too long). Look at Github. Speed vs. integration/trust/maintenance (the work of a distro)
- snapcraft 2.0 (learn more about your first snap): reduce the amount of work to package software. Install software together transactionally.
An overview of a next-gen filesystem
Another talk I found interesting was the talk about bitrot, and filesystems like btrfs and ZFS. Best to read the presentation, and the article that was referenced.
Scaling GlusterFS at Facebook
A talk by Facebook is usually quite full, and I was interested in how they were using GlusterFS and if anyone has managed to successfully run a database over it yet (no). This was a talk given by Richard Wareing who’s been at Facebook for over 5 years:
- GB’s to many PBs, 100’s of millions of files. QPS (FOPs) is 10s of billions per day, namespace (volume), TBs to PBs and Bricks: 1000’s. Version 3.3.x is when they started and now they use 3.6.x (trail mainline closely)
- Use cases: archival, backing data store for large scale applications, anything that doesn’t fit into other DBs
- RAID6, controller is enterprise grade, storage is more consumer grade
- Primarily using XFS, and are starting to use btrfs (about 20% of the fleet run on it)
- closed source AntFarm, JD, and their IPv6 support (they removed IPv4 support). They have JSON Statistic dumps which they contributed upstream.
- a good mantra, pragmatism over correctness
Some expo hall chatter
There was plenty to followup post-SCALE14x with many having questions about MariaDB Server, or wanting to buy services around it from MariaDB Corporation. I learned for example that Rackspace maintains their own IUS repository of packages they think their customers will find important to use. The idea behind it is that its Inline with Upstream Stable. Naturally you will find MariaDB Server as well as packages for all the engines like CONNECT.
Its incredibly rewarding to note that pretty much everyone knew what MariaDB Server was. Its been a long journey (six years!) but it sure feels sweet. Ilan and his team put on a great SCALE so I can’t wait to be back again next year.
