This week I’ve been writing based on my linux.conf.au 2014 talk, which you can watch the recording of.

Also see Part 1, Part 2, Part 3 and Part 4. My feed feel off Planet MySQL for a bit so you may have missed those posts.

Now we head into the era of acquisitions… there have been a few in …

There was once a big hooplah about the MySQL Storage Engine Architecture and how it was easy to just slot in some other method of storage instead of the provided ones. Over the years I’ve repeatedly mentioned how this wasn’t really …

I’d had some difficulty manually creating my own windows service for MariaDB (worked fine from the installer), but it was due to the way I was creating it, so I wanted to share the proper approach:

Old Way:

sc create "maria55" binpath= "\"C:/Program Files/MySQL/MariaDB 5.5/bin/mysqld\"
\"--defaults-file=C:/Program Files/MySQL/MariaDB 5.5/data/my.ini\""
DisplayName= "Maria55" start= "auto"

New Way:

sc create "maria55" binpath= "\"C:/Program Files/MySQL/MariaDB 5.5/bin/mysqld\"
\"--defaults-file=C:/Program Files/MySQL/MariaDB 5.5/data/my.ini\" maria55"
DisplayName= "Maria55" start= "auto"

The key is adding the name, maria55, after the –defaults-file=.. option, but still within the “” that belong to “binpath”.

This extra parameter exists so that mysqld knows whether or not it was started as a service or not.

Without it, the server does not know, and …

I am very pleased to say that earlier today, SkySQL announced it has raised $4 Million in Series A Round Funding.

Let me post the main part of the press release here:

SAN JOSE – April 18, 2012 – SkySQL, the first choice in affordable database solutions for the MySQL® and MariaDB® databases in the enterprise and the cloud, today announces that the company has raised $4 million in Series A funding from a number of investors, including OnCorps, an elite peer-based community of veteran technology investors and advisors committed to bringing better, cost-disruptive technologies into the mainstream.

SkySQL will primarily use the investment to fund growth in its new product development, including adding critical positions. This is the …

Well, as you or may not have heard, MariaDB 5.5 (5.5.23) was declared GA last week!

It was only about 6-ish weeks ago that MariaDB 5.5 had been released as alpha, so the fact it’s already GA is excellent news for all MariaDB users (and MySQL 5.5 users looking to migrate).

Some of the 5.5 enhancements include:

• Significantly more efficient thread pool, comparable in functionality to the closed source feature in MySQL Enterprise.
• Non-blocking client API Library (MWL#192)
• @@skip_replication option (MWL#234)
• SphinxSE updated to version 2.0.4.
• “extended keys” support for XtraDB and InnoDB
• New INSTALL SONAME statement
• New LIMIT ROWS EXAMINED optimization.
• mysql_real_connect() Changes
  In MySQL, and in MariaDB versions before 5.5.21, mysql_real_connect() …

This is another, in-case-you-missed-it, but it is definitely worth mentioning again:

MariaDB 5.3 is now GA

So, if you’re using MariaDB 5.1 or 5.2, I’d definitely recommend upgrading to the new MariaDB 5.3.

Also, if you’re a Windows user using MySQL 5.1, I’d highly consider making the switch to MariaDB 5.3 due to all of the Windows-specific improvements in it.

MariaDB 5.3 Enhancements:

• Subquery optimizations
• Semi-join subquery optimizations
• Non-semi-join optimizations
• Subquery Cache
• Subquery Optimizations Map
• Optimizations for derived tables and views
• Disk access optimization
• Join optimizations
• Index Merge improvements
• Optimizer control
• NoSQL-style interfaces
• Group commit for the binary log
• Replication and binary logging enhancements …

In case you didn’t notice it last week, MariaDB 5.5 (5.5.20, specifically) has been released.

It’s a release I’ve been looking forward to for a while now, so I’m very excited that it’s now available!

Note that it is currently ‘alpha’ since it is the very first release of MariaDB 5.5. However, it is not your typical new ‘alpha’, so I would expect it to be GA in the not-so-distant future (please don’t quote me on this though, as I have no idea of the true time table – but the goal is for the next 5.5 release to be ‘beta’).

You can download MariaDB 5.5 from the following location:

I just wanted to share my steps for building MariaDB 5.3 on Windows. (Note, this is not much different than the instructions Wlad posted here).

But, things are not always so smooth, and of course I ran into a couple small issues, so I wanted to share my outputs plus those issues and their solutions (once again many thanks go to Wlad!) for those out there who might encounter the same.

Here are the steps to build:

1. Download MariaDB 5.3 and extracted to C:\mariadb-5.3

2. cd C:\mariadb-5.3

3. mkdir bld

4. cd bld

5. cmake .. -G "Visual Studio 9 2008"

6.     cmake --build . --config relwithdebinfo --target package

* …

Recently, I found myself needing MariaDB 5.1.60 for Windows for some testing purposes. Therefore, I needed to build it from source. I ended up using what I’d call a “blend” of the commands listed in this “how-to” and the readme file INSTALL-WIN-SOURCE, so I thought I’d post those steps.

1. Download 5.1.60 MariaDB source from here.

2. cd C:\mariadb-5.1

3. win\configure.js

4. cmake .

5. VS: File -> Open -> Solution -> MySql.sln
6. VS: Build -> Build Solution
7. VS: Right-click “PACKAGE” -> Build (in “Solution Explorer” View)

That’s it.

Let’s fire it up:

MariaDB> select version(); …

I’m often wondering what version of the InnoDB Plugin is included with which version of MySQL (or MariaDB). The MySQL changelogs used to denote which version of the InnoDB plugin was included with that particular release of MySQL, but sadly this is no longer the case.

Therefore I’ve compiled a comprehensive list which contains all of this info, and then some (and note all InnoDB Plugin changelog links are provided at the bottom).

Hope you find it helpful
