2016 MariaDB Developers Meetup Presentations

I’ve collected slides and videos from several of the presentations given at the MariaDB Developers Meetup in Amsterdam, 6-8 October 2016. This meetup was kindly hosted by Booking.com. The presentations are listed here in roughly the order they were given. If I have both the slides and video for a given talk I link to both, otherwise I just link to what I have. The video is of poor quality as it was livestreamed to Periscope from a handheld mobile phone. Network issues also mean the streams sometimes dropped and had to be restarted. I will update this post as a receive slide decks from other speakers. …

Thoughts on MariaDB Server 10.3 from MariaDB Developers Meeting in Amsterdam, part 1

I had the honor of leading a session on Saturday, during the MariaDB Developers Meeting in Amsterdam, brainstorming around MariaDB Server 10.3. It’s definitely time to do that since MariaDB Server 10.2 has entered beta stage. In case you have missed that, I’ve wrapped up what’s included in 10.2 so far in a blog post on my employer’s site. In addition to the features mentioned in that blog post there are a couple of features still coming in 10.2 of which the most notable is that the MyRocks engine will be included. More about this later in another article. …

Eating our own dog food – Running JIRA on MariaDB

A couple of weeks ago we announced that we were moving from a hosted instance of JIRA to our self hosted instance. The main reason was that we hit 2000 active users in the hosted instance of JIRA and that is the upper limit that it  supports. We obviously wanted to allow more people to be active in reporting and commenting on bugs and features for MariaDB. That’s why we set up our own instance, which now is up and running at jira.mariadb.org.

Thank you Atlassian, the company behind JIRA, for providing the hosted instance of JIRA for the MariaDB project over the last three years! …

What’s new in MariaDB Connector/C 3.0 – Part I: SSL

New SSL alternatives

SSL connections in previous versions of MariaDB Connector/C are based on the OpenSSL library. But because of the OpenSSL heartbleed bug, licensing problems and the lack of support for different transport layers, we decided to add support for alternative SSL implementations.

That’s why Connector/C 3.0 can use not only OpenSSL, but also

  • GnuTLS (http://www.gnutls.org)
  • SChannel (Windows only)

On Windows Connector/C 3.0 uses SChannel by default and does not require any external SSL libraries.

Currently the SSL implementation must be selected when Connector/C is compiled. One does it by setting WITH_SSL cmake variable to one of the OPENSSL, GNUTLS, SCHANNEL, or OFF to have no SSL support at all. …
