MySQL 5.5 is GA!
Employee_Team +18 Vote Up -0Vote Down
It is my pleasure to announce that MySQL 5.5 is now GA and ready for production deployment.  You can read Oracle's official press release here.

I am excited about 5.5 because of the performance and scalability gains, new replication enhancements and overall improved technical efficiencies.  Congratulations and a sincere "Thanks!" go out to the entire MySQL Community and product engineering teams for making 5.5 the best release of MySQL to date.

MySQL 5.5: Improved manageability, efficiency for InnoDB
Employee_Team +2 Vote Up -0Vote Down
In my continuing blog series on MySQL 5.5 features (see performance/scale and replication entries) today I covering some of the new InnoDB manageability and efficiency options.  5.5, with the newly re-architected InnoDB, provides better user control over internal InnoDB settings so things like performance, scale and storage can easily be monitored, tuned and optimized for specific use cases and application loads.

Along these lines, some of the key advances and features available in MySQL 5.5 and InnoDB are:
  • Faster Index Creation - MySQL 5.5 can now add or drop indexes without copying the underlying data of the entire

Transforming Telecommunications with Web 2.0
Employee_Team +2 Vote Up -0Vote Down
The convergence of telecommunications onto IP (Internet Protocol) based networks is revolutionizing today's communications industry. Communications Service Providers (CSPs) are challenged to deliver compelling new personalized services with greater agility and lower costs than ever before.

Whether they are looking to deploy new Web/Telco 2.0 applications to mobile Internet users or consolidating subscriber data within the network to support greater service personalization and targeted communications, the database plays a key role in enabling new services.

We believe MySQL is pretty much unique in the industry by providing the insight and experience to marry the innovation and speed of the Web with the proven capabilities of the carrier network. MySQL is deployed in 9 of the top 10 most trafficked sites on the web [1] including Google, Facebook

MySQL 5.5: What's New in Replication
Employee_Team +11 Vote Up -0Vote Down
In my continuing MySQL 5.5 blog series, today I am covering what's new on the replication front.  MySQL replication is my favorite server feature and what drew me to MySQL during my tenure with Embarcadero Technologies.  Others seem to agree as based on community and customer surveys, MySQL replication is the most popular and widely used database feature.  Mostly because it is easy to set up and ease, it enables scalability and provides a pretty robust solution for data redundancy, backup and overall availability.  In MySQL 5.5 replication has been enhanced in response to user requests that MySQL replication:

  • Ensure data consistency between master and slave servers
  • Immediately detect if replication is not working
  • Allow a crashed slave to automatically recover from the master relay

Get The Facts: MySQL Licensing and Pricing
Employee_Team +12 Vote Up -3Vote Down
The confusion about whether MySQL Community Edition still included InnoDB seems now to have dissipated. Thank you to Sheeri Cabral, Darren Cassar and all of you who helped correct the misperception created by catchy headlines. In part, the confusion was caused by people assuming that the MySQL Classic Edition (an option for embedding that has been around for a long time) is the same as MySQL Community Edition...not so. We have made appropriate changes to our web page ( to clarify this.  [Read more...]
MySQL 5.5: Performance and Scalability Unleashed!
Employee_Team +8 Vote Up -0Vote Down
MySQL 5.5 is set to ship GA soon so I thought I would create a series of blogs that highlight the key new features  I will start with a rundown of where we have made improvements and then expand into details as things progress.  MySQL 5.5 merges the technical architectures of the MySQL database with the InnoDB storage engine so that the two should now be considered one and will move in tandem for the most part from now on (We can do this now that Oracle owns both...)  That said, the key things to know about MySQL 5.5 and the re-architected InnoDB storage engine are:

  • Oracle's InnoDB is the default database storage engine
  • Performance and Scalability on Windows is on par or better than for other platforms
  • MySQL now fully utilizes the computing power of modern multi-core architectures across all

Not excited about paying for MySQL monitoring for your enterprise?

I think most people will agree that one of the biggest advantages of MySQL Community Server is that it’s free. Being free doesn’t get you a multi-million user community though; MySQL offers a great array of transactional engines, advanced high-availability features, robust I/O performance, and it powers many of the top-500 internet sites. When it […]
A simple load test script in Python
+1 Vote Up -0Vote Down

Lately I’ve had to do some environment load testing so I wrote this quick script. It can be modified as needed but the basic idea is that it spawns $x threads (–threads) and then sends two connections (or however many you want with –per-connection=) per thread to the URL (–url=). You can have it wait a configurable time between connections as well (–wait=).

The url is appended with a 32 character randomized string so that any database/caching on the backend of the site isn’t serving data from a warm cache. You can hunt down the string length for 32 and change it to whatever you want. Feel free to change and use as needed, just keep my info at top.

UPDATE: An on-demand replay for the webinar discussed below is available here:

And there is a new whitepaper for MySQL Replication posted here:

The recent announcement of the MySQL 5.5 Release Candidate included some pretty staggering increases in performance and scalability. 

Replication is also an area where many enhancements have been made including semi-synchronous replication, replication heartbeating, fsync tuning, relay log recovery, per-server replication filtering, etc.

On Tuesday 12th October, Dr. Lars Thalmann

+0 Vote Up -0Vote Down

There’s a new version of the dbbenchmark tool available. Now we’re creating the MySQL connection pool thread count based on automatic reporting of core quantity. There is still the same method to set the thread count manually if you are interested in finding your system’s thread limits. Download the MySQL benchmarking script now and add your server performance to the community database of results!
