Drizzle 7 plugins

Last week I wrote about my experience compiling Drizzle 7 on Mac OS X 10.6. Then David Shrewsbury informed me of his nearly identical blog post: Installing Drizzle from source on OS X. Once Drizzle 7 was running on my box, I immediately looked to see what plugins where available because Drizzle uses a lot of plugins and they are one of its notable differences from MySQL. In my humble opinion, Drizzle’s plugins will primarily influence how database professionals evaluate and decide whether or not to use Drizzle because so many of Drizzle’s features are plugins. Therefore, let’s look briefly at some the plugins included with Drizzle 7.

The plugin directory of the Drizzle 7 tarball lists 79 plugins. Each plugin …

SQLStats 1.3 released

I have released SQLStats 1.3 now, and it is available for download from sourceforge. The changes are small:

  • Cleaned up the build script a bit.
  • Fixed a bug that caused statements to be counted twice.
  • Made statement comparison non case sensitive.
  • A small fix to the normalizer, that would miss a few statements in some cases.

SQLStats is a plugin for MySQL 5.5 and up that allows live monitoring of SQL statements, without using the general query log and with the added benefit of managing statements with the literals removed. read more in my previous blog-post in the subject.


Monitoring MySQL SQL statements the way it SHOULD be done!

You may have read a previous post of mine, back in April this year, where I wrote about using the MySQL 5.5 Audit interface to SQL Statement monitoring. There was a bunch of comments and some ideas, but not much happened. Until now that is.

Hereby I release the first version of SQLStats, which is a much enhanced version of what I described in the previous post. This is a MySQL Plugin for MySQL 5.5 that allows you to monitor the most recently executed, and the most frequently executed statements using 2 INFORMATION_SCHEMA tables. The thing is not very complex, to be honest, but it does do the job. So what was the job then? Well, looking at what this plugin does, it goes something like this:

  • Allows you to monitor ALL SQL statements executed by the server.
  • The SQL statements are "normalized", …

MySQL 5.5.7 - Can we trust it being RC, or?

I just saw that MySQL 5.5.7 RC had been released, and reading the releasenotes made me more than a fair bit suspicious. In some kind of general agreement on what constitutes a "beta" release, this is when the software has reached a level of maturity when no more major features are to be introduced. MySQL (and many others) has broken that rule at times, and the rule is not enforced or something.

What constitutes an RC release though, in my mind, but I really want to know what you think, is software that is really 100% feature complete. There may be, but hopefully there aren't, even any major bugs to iron out. In short, it is "A Candidate to Release", and as close to GA as you can get. I have not seen this rule broken much, really.

With MySQL 5.5.7, this is an rc, as was the previous release, 5.5.6, and this time there is a really major feature introduced between these two release, pluggable authentication. And before I …

Book review: MySQL 5.1 plugin development
MySQL 5.1 Plugin Development,
by Sergei Golubchik and Andrew Hutchings.
Packt Publishing, 2010.
Executive summary: Highly recommended. If you want to develop MySQL extensions, buy this book. It's a must, written by two expert professionals who probably know more than anyone else on this matter. The book is full of practical examples explained with the theoretical information necessary to make it stick.

This book fills a gap in the world of MySQL documentation. Although the MySQL docs are extensive and thorough, to the point that sometimes you wished that the writers were less verbose and stick more to the topic, when …

Second Drizzle Beta (and InnoDB update)

We just released the latest Drizzle tarball (2010-10-11 milestone). There are a whole bunch of bug fixes, but there are two things that are interesting from a storage engine point of view:

  • The Innobase plugin is now based on innodb_plugin 1.0.6
  • The embedded_innodb engine is now named HailDB and requires HailDB, it can no longer be built with embedded_innodb.

Those of you following Drizzle fairly closely have probably noticed that we’ve lagged behind in InnoDB versions. I’m actively working on fixing that – both for the innobase plugin and for the HailDB library.

If building the HailDB plugin (which is planned to replace the innobase plugin), you’ll need the latest …

TaskFreak! v0.6.2 – Alter Search Plugin

Background Knowledge

The Search Plugin for TaskFreak! created by DaDaemon and xdu v0.0.1 (March 26, 2007) was designed to create a simple, quick search capability of the tasks title and description. As well it only searched through he current task view (tasks visible at the time) and tasks that are not completed. For some this was not what was desired and would rather have the Search Plugin search through all tasks weather completed or not and as well search through the comments of tasks along with the title and description. I’ll show you how this is done using Searcher, bchristie and davidlmansfield instructions posted on the TaskFreak! Forums.

Solution – Add the Ability to Search All Tasks

Edit the “index.php” located in …

Ease of Switching to the InnoDB Plugin and the Numerous Benefits

In my last post, I discussed how to troubleshoot InnoDB locks using the new InnoDB Plugin’s new Information Schema tables.

However, that got me to thinking about how many MySQL 5.1 users who have still not switched to use the plugin as opposed to the built-in version of InnoDB.

There are many advantages to using the plugin as opposed to the built-in version (aside from just the new I_S tables, and more importantly, numerous performance enhancements), and it’s breeze to set up, so I wanted to provide a quick start guide to using the new InnoDB plugin.

Note that the …

Trace SQL From the Database to the Source Code with MySQL Enterprise Monitor

OK, you found the problem SQL statement that was affecting your server’s performance, now where did it originate?

The new MySQL Enterprise Plugins for Connector/J and Connector/NET send query statistics, including the source location for each query, directly to the MySQL Enterprise Monitor.

Figure 1 is a screenshot of new source location feature.

Figure 1. Source Location

Figure 2 shows the standard query statistics, which are collected in the query analyzer.  In both cases, the statistics are gathered by the MySQL Connector and the Plugin, not MySQL proxy.

If you’re a MySQL Enterprise customer, you can …

MySQL University: Securich - Security Plugin for MySQL (rerun)

This Thursday (June 10th, 14:00 UTC), Darren Cassar will rerun his February 25 presentation of Securich - Security Plugin for MySQL. (Recording of the session failed in February; hopefully it will succeed this time.) According to Darren, the author of the plugin, Securich is an incredibly handy and versatile tool for managing user privileges on MySQL through the use of roles. It basically makes granting and revoking rights a piece of cake, not to mention added security it provides through password expiry and password history, the customization level it permits, the fact that it runs on any MySQL 5.0 or later and it's easily deployable on any official MySQL binary, platform independent.
More information here: …
