Speaking at Percona Live Europe Amsterdam

I’m happy to speak at Percona Live Europe Amsterdam 2016 again this year (just look at the awesome schedule). On my agenda:

I’m also signed up for the Community Dinner @ Booking.com, and I reckon you should as well – only 35 spots remain!

Go ahead and register now. You should be able to search Twitter or the Percona blog for discount codes :-)

What’s next

I received an overwhelming number of comments when I said I was leaving MariaDB Corporation. Thank you – it is really nice to be appreciated.

I haven’t left the MySQL ecosystem. In fact, I’ve joined Percona as their Chief Evangelist in the CTO Office, and I’m going to focus on the MySQL/Percona Server/MariaDB Server ecosystem, while also looking at MongoDB and other solutions that are good for Percona customers. Thanks again for the overwhelming response on the various social media channels, and via emails, calls, etc.

Here’s to a great time at Percona to focus on open source databases and solutions around them!

My first blog post on the Percona blog – I’m Colin Charles, and I’m here to evangelize open source databases!, the press release.

Speaking in July 2016

  • 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.

MariaDB Berlin Meetup Notes & Slides

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.

  1. Monty talked about improving the speed of connections to MariaDB Server, some work he’s just pushed fairly recently to the 10.2 tree.
  2. Dipti spoke about MariaDB ColumnStore and it is now clear we’ll see some source/binary drop by the end of May 2016.
  3. 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).
  4. Jan spoke about InnoDB in 10.2.
  5. Lixun Peng spoke about a fairly interesting feature, the idea to flashback via mysqlbinlog and 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.
  6. Kolbe spoke about data at rest encryption using the MariaDB Amazon AWS KMS plugin.
  7. 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.
  8. 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.
  9. Johan Wikman gave us an introduction to MariaDB MaxScale, which started off the talks on MaxScale.
  10. Markus talked about the readwritesplit plugin.
  11. Massimiliano went into the Binlog server.
  12. 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.
  13. 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.
  14. 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.

(tweet) Summary of Percona Live 2015

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.

  • MySQL 5.7 has new optimizer hint frameworks. New cost based optimiser. Generated (virtual) columns. EXPLAIN for running thread #perconalive
  • MySQL 5.7 comes with the query rewrite plugin (pre/post parse). Good for ORMs. “Eliminates many legacy use cases for proxies” #perconalive
  • MySQL 5.7 – native JSON datatypes, built-in JSON functions, JSON comparator, indexing of documents using generated columns #perconalive
  • InnoDB has native full-text search including full CJK support. Does anyone know how FTS compares to MyISAM in speed? #perconalive

  • google encryption: mariadb uses the api to have a plugin to store the keys locally; but you really need a key management server #perconalive
  • Google encryption: temporary tables during query execution for the Aria storage engine in #MariaDB #perconalive
  • find out more about google mysql encryption — https://code.google.com/p/google-mysql/ or just use it at 10.1.4! https://downloads.mariadb.org/mariadb/10.1.4/ #perconalive
  • Encrypting MySQL data at Google – Percona Live 2015 #perconalive http://wp.me/p5WPkh-5F
  • The @WebScaleSQL goals are still just to provide access to the code, as opposed to supporting it or making releases #perconalive
  • There is a reason DocStore & Oracle/MySQL JSON 5.7 – they were designed together. But @WebScaleSQL goes forward with DocStore #perconalive
  • So @WebScaleSQL will skip 5.7, and backport things like live resize of the InnoDB buffer pool #perconalive
  • How to view @WebScaleSQL? Default GitHub branch is the active one. Ignore -clean branches, just reference for rebase #perconalive
  • All info you need should be in the commit messages @WebScaleSQL #perconalive

Speaking in March 2016

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.
