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. …
The 2016 MariaDB Developers Meetup will be taking place in Amsterdam, from 6 – 8 October.
The meetup will last for three days and you can join for the whole time, or as little time as you wish.
The schedule of this unconference will be drafted in a public spreadsheet. Initially, anyone attending can help set the schedule by adding sessions, as well as voting for session’s they’re interested in, by incrementing the vote counter. Based on this, the schedule will be drawn up.
The event venue and lunches are sponsored by Booking.com. …

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! …

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. …

MariaDB Connector/J has evolved a lot during the year. In this post I will talk about the failover capabilities in the connector and give some guidance on how to use them in some certain cases. One other important new feature that I’ll cover in a later article is the fact that MariaDB Connector/J can do load balancing over several servers now as well.
To start off with we’ll need the connector itself. Do either of the following to get version 1.2.3 of MariaDB Connector/J which is the newest stable version as of writing:
- Download the binary from https://mariadb.com/my_portal/download (requires login) .

MariaDB 10.1 shipped a few days ago, so it’s now a good time to focus on another important event. Last week we had a three day MariaDB developers meeting. It took place in Amsterdam (Oct 13-15). Meetings like this tend to have a great impact on the roadmap of the product. Booking.com was very kind to offer their facilities for the developer meeting.
Thank you Booking.com!
The day before the developer meeting there was a MySQL meetup arranged at eBay’s office in Amsterdam since, naturally, a lot of MariaDB developers were already in town for the developers meeting. …
