TokuDB vs Percona XtraDB using Tokutek’s MariaDB distribution
+1 Vote Up -0Vote Down

Following are benchmark results comparing Tokutek TokuDB and Percona XtraDB at scale factor 10 on the Star Schema benchmark. I’m posting this on the Shard-Query blog because I am going to compare the performance of Shard-Query on the benchmark on these two engines. First, however, I think it is important to see how they perform in isolation without concurrency.

Because I am going to be testing Shard-Query, I have chosen to partition the “fact” table (lineorder) by month. I’ve attached the full DDL at the end of the post as well as the queries again for reference.

I want to note a few things about the …

Enabling the Verbose InnoDB Lock Monitor in MariaDB and Percona Server for XtraDB+ and XtraDB
+0 Vote Up -0Vote Down

I enabled the InnoDB Lock Monitor in my MariaDB 5.5 instance (using XtraDB+ as the InnoDB – which is the default in MariaDB) and noticed that while the SHOW ENGINE INNODB STATUS was being logged to the error log, it wasn’t logging the “additional” lock information – it just looked like the plain ‘ole INNODB STATUS.

Long story short, Percona added a new variable so one has better control over what gets logged:

innodb_show_verbose_locks

If off (default), then the InnoDB Lock Monitor logs the normal INNODB STATUS, and if enabled, then it logs …

InnoDB Plugin Version Numbering in MySQL and MariaDB
+2 Vote Up -0Vote Down

As some of you may or may not know, I’ve maintained a list of all InnoDB Plugin versions as they’ve historically contained a different version (entirely different numbering scheme) than the MySQL distribution they were included with.

This list was most helpful for troubleshooting various InnoDB issues when the plugin may (or may not) have been involved, and/or for benchmarking, etc. And it’s fair to say it was more useful when the InnoDB plugin was not the mainstream, which it is now.

However, with the latest releases, in MySQL and MariaDB, the “InnoDB Version” simply matches the “MySQL …

How to Enable the Original InnoDB Plugin in MariaDB 5.5
+7 Vote Up -0Vote Down

As I mentioned here, there is a slight change for enabling the [original] InnoDB Plugin in MariaDB 5.5 (as compared to how you would enable it in 5.1).

Remember, in MariaDB 5.5, if you do not “enable” (i.e., add anything to the config file to do so) the InnoDB Plugin in MariaDB 5.5, you’ll end up with XtraDB+ for your InnoDb plugin. However, if you do “enable” the InnoDB plugin, then you end up with the original InnoDB plugin provided by Oracle/InnoDB.

The change is that the plugin file (.dll for Windows, .so file for Linux) which was previously named “ha_innodb_plugin.dll” is now just …

Building XtraDB on Windows
+1 Vote Up -0Vote Down

As you may or may not know, Windows is not yet a supported platform for XtraDB.

I thought I’d try to build it, and see what happens:

  1. Download XtraDB 5.5 Source
  2. cd C:\xtradb-5.5
  3. mkdir bld
  4. cd bld
  5. cmake ..
  6. VS08: File -> Open -> Solution -> C:\xtradb-5.5\bld\MySQL.sln

Build Ended With:

========== Build: 70 succeeded, 17 failed, 2 up-to-date, 10 skipped ==========

Building MariaDB 5.1 on Windows
+2 Vote Up -0Vote Down

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 …

InnoDB Plugin Version History
+4 Vote Up -0Vote Down

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
