Last night, after my previous blog post, everyone in attendance at the SkySQL developer meeting in Barcelona gathered for dinner at El Cangrejo Loco, which, if my High School Spanish is working, translates as The Crazy Crab. After the excellent food, the tradition of singing at MySQL/MariaDB developer meetings was preserved.

Today the MariaDB developers in attendance at the SkySQL developer meeting in Barcelona got together to work on plans for MariaDB 10.1. We also paused for a group photo:

Many tasks have been identified for possible inclusion in 10.1. Some have already been marked as such in JIRA. A summary is available for those that are interested. More will be added as the plans for 10.1 firm up, so check back.

Several MariaDB developers are attending SkySQL’s annual engineering meeting being held this week in Barcelona. While some of the discussions are SkySQL-specific (customers, internal projects, and so on), there are, naturally, lots of MariaDB discussions happening.

Patrik Sallner, CEO of SkySQL, opened the meeting this morning with a short presentation about SkySQL’s goals for 2014. While the plan includes standard business-like things that include growing the company and sales goals, the top two goals for 2014 are:

1. Help make MariaDB into the leading open source database

2. Help increase awareness and adoption of MariaDB

Looking back at 2013, it was an excellent year for MariaDB. It is now the default database in Fedora, OpenSUSE, Mageia, and others and it is included in the recently released Red Hat Enterprise Linux 7  preview. During the last …

MariaDB is in Debian/unstable now, and its great to see that we already have a Japanese po-debconf translation (in under a month!). The last time I was in Tokyo, Japan we seemed to have great interest in MariaDB, especially with the backing of MariaDB.com/SkySQL investment dollars and the MariaDB Foundation to keep things real.

For me, I’m happy to go back to Tokyo to talk to users about MariaDB. If you’re in the area on Tuesday, 18 February 2013, there is a …

On last Wednesday morning I gave my talk at linux.conf.au 2014. You can now view and download the recording of it here:

MaxScale is the new proxy server from the SkySQL/MariaDB team. It provides Connection Load Balancing (CLB) and Statement Load Balancing (SLB) out of the box. This post is a [relatively] quick “how to” install, configure and test SLB with the read/write splitting module.

Step 1 - Server preparationIf you do not have many HW resources, you may run everything on a single Linux instance, but the best way to test MaxScale is to use at least 4 servers: one for MaxScale and for the client apps, one as Master and two as slaves - so, 4 in total. In this post I am going a bit further, I will use 5 servers:
Max 0 - For client apps (192.168.56.20)
Max 1 - The master server (192.168.56.21)
Max 2 - The first slave (192.168.56.22)
Max 3 - The second slave (192.168.56.23)
Max 4 - The third slave (192.168.56.24)
Max 6 - The MaxScale server (192.168.56.26)

In order to do proper tests …

MySQL Cluster is a popular backend for FreeRADIUS, as it provides a scalable backend to store user and accounting data. However, there are situations when the backend database becomes a centralized datastore for additional applications and services, and needs to take a more general-purpose role. NDB usually works very well for FreeRADIUS data, but for wider use cases and reporting type applications, InnoDB can be a better storage engine. For users who need to keep their data in InnoDB and still benefit from a highly available clustered datastore, Galera Cluster can be an appropriate alternative.

In this post, we will show you how to deploy FreeRadius both with MySQL Cluster and Galera Cluster to store user and accounting data. All servers are running CentOS 6.4 64bit.

FreeRadius Deployment with Galera

We will deploy a two-node FreeRadius cluster …

In many parts of the MySQL world, whether you have users, developers or administrators of MySQL, the season holidays are for family, relax, prayers, travel, or they are simply a moment where you can enjoy what you like or care most about.

For me, this time is dedicated to my family, but also to deeper thoughts around the strategies to adopt in short and long term. My work nowadays, as the work of many others, is ruled by quick decisions, by the "time to market” - whatever “market" means in a specific context. Decisions must be made in meetings that are time-boxed in one hour or even less. In the end, you accumulate so much work and high priority tasks that you do not have enough time to prepare the topics adequately.

I thought I could summarise my thoughts for the past year and for the near future, from a technical and from a business perspective.

A transient 2013To me, 2013 was a transient …

Chinese and Japanese and Korean (CJK) text usually has no spaces between words. Conventional full-text search does its tokenizing by looking for spaces. Therefore conventional full-text search will fail for CJK.

One workaround is bigrams. Suppose the text is

册免从冘

There should be three index keys, one for each two-character sequence:

册免, 免从, and 从冘.

Now, in a search like

SELECT * FROM t WHERE MATCH(text_column) AGAINST ('免从');

a bigram-supporting full-text index will have a chance. It's wasteful and there will be false hits whenever the bigram isn't really a "word", but the folks in CJK-land have found that bigrams (or the three-character counterpart, trigrams) actually work.

One way to get bigrams for MySQL or MariaDB is to get mroonga.

Why care about Yet Another Storage Engine)?

The MariaDB project is pleased to announce the immediate availability of MariaDB 10.0.7. This is a Beta release. See the Release Notes and Changelog for detailed information on this release and the What is MariaDB 10.0? page in the MariaDB Knowledge Base for general information about the MariaDB 10.0 series.

A few things to note recently, amongst MariaDB in distributions. 

1. Ubuntu keeps MySQL 5.5 despite MariaDB’s success. There’s a lot of reasons for this, but remember the key takeaway here is MySQL 5.5 & the fact that MariaDB wasn’t even in Debian yet when the decision was made.
2. MariaDB is now inside of Debian/sid – check out the packages.
3. RHEL 7 comes with MariaDB 5.5 as a default; this is a good thing.

Now, from a distribution standpoint, we’re looking at starting to ship 10.0 as …
