MariaDB 10.0.7 Overview and Highlights

MariaDB 10.0.7 was recently released (it is the latest MariaDB 10.0), is currently “beta”, and is available for download here:

I just wanted to note a couple of the main highlights, which are:

  1. XtraDB storage engine was upgraded to the 5.6 version. Now one can use XtraDB with MariaDB 10.0. Unlike MariaDB 5.5, in 10.0 XtraDB is not the default engine, the default is InnoDB, and XtraDB is available as a dynamic plugin.
  2. OQGraph storage engine was upgraded to the version 3. Unlike OQGraph v2, that stores all the data in memory, new OQGraph v3 stores them in a table of another storage engine, on disk. Which makes your graphs persistent and also can support much larger graphs. See the OQGraph documentation for details.
  3. A new plugin metadata_lock_info was added. It implements a new table INFORMATION_SCHEMA.METADATA_LOCK_INFO that shows active metadata locks.

And for reference, the full 10.0.7 changelog can be viewed here:

Hope this helps.

Tracking Server Variables, Documentation, Manuals, Changelogs for MySQL, InnoDB, MariaDB, and XtraDB

I find myself constantly looking up server variables (and manuals and changelogs) for MySQL, MariaDB, and XtraDB, which versions they are in, and so forth. So I finally created a couple pages which contain the links to all of these various bits of information across the various flavors of MySQL.

I’ve been using them every day, so I thought some others might want to bookmark these as well.

I’ve created the following:

o Changelogs
o Documentation
o Server Variables
o InnoDB Plugin Versions

The Changelogs page contains links for MySQL 3.23 up through 5.6, MariaDB 5.1 – 5.3, XtraDB 5.1 – 5.5, Xtrabackup 1.3 – 1.6, Connector/ODBC, Connector/.NET, Connector/J, Connector/C++, Connector/MXJ, and MySQL Proxy.

The Documentation page contains links for the MySQL manuals 3.23-5.6, InnoDB Plugin 1.0 – 1.1, MariaDB 5.1 – 5.3, XtraDB 5.1 – 5.3, and Xtrabackup 1.6.

The Server Variables page contains the links for the MySQL Server variables for all versions, the server variable cross-reference chart, all InnoDB startup variables, and new MariaDB options.

And lastly, the InnoDB Plugin Versions (which I did mention a couple weeks ago) contains all InnoDB Plugin version information, such as which InnoDB plugin is included with which MySQL release, as well as links to changelogs, and other relevant information.

If you find yourself wishing there were some other links added, just post me a comment and I’ll try to get it added asap.
