Configuring MySQL Server for Optimal Performance
Employee_Team +0 Vote Up -0Vote Down

Configuring MySQL Server, with the dozens of options available, has always been perceived as a bit of a black art. In MySQL Database 5.6, configuring your MySQL server for optimal performance is easier than ever before.

In the MySQL for Database Administrators course you can learn more.

MySQL 5.6 is configured to work faster out of the box in a wide range of installation scenarios and it is easier than ever to set up the server by adjusting only a small number of settings which cause others to be set. In addition, you get a new default my.cnf file with instructions guiding your through adjusting key settings. The

MySQL as a Key Value Store (KVS) - Why, some background and some more tests
+1 Vote Up -0Vote Down
You might have seen my attempts at testing MySQL as a Key Value Store (KVS) (here and here), i.e. used like MongoDB, and I have had some comments to those. Above all, many wanted to know the details of my test environment. To be honest, this started off as a very simple thing, but it turned out a bigger than I thought, so I guess its reasonable to give some background. I apologize for not giving you this background before, but as I said, my initial intention was to just run bog standard MongoDB versus MySQL and see what happened.  [Read more...]

$1000 per hour Servers, Anyone?
+0 Vote Up -0Vote Down

Read the original article at $1000 per hour Servers, Anyone?

Amazon's spot market for computing power is set up as an open market for surplus servers. The price is dynamic and depends on demand. So when demand is low, you can get computing instances for rock bottom prices. When you do that you normally set a range of prices you're willing to pay. If it goes over your top end, your instances get killed and re-provisioned for someone else. Obviously this wouldn't work for all applications, like a website that has to be up all the time, but for computing power, say to run some huge hedge fund analytics, it might fit perfectly.

A recent post on SEO MOZ alerted us to an interesting story where spot instances spiked to

PuppetConf and the state of devops
+0 Vote Up -0Vote Down

It’s been some time now that we’ve been talking about devops, the pushing together of application development and application deployment via IT operations, in the enterprise. To keep up to speed on the trend, 451 CAOS attended PuppetConf, a conference for the Puppet Labs community of IT administrators, developers and industry leaders around the open source Puppet server configuration and automation software. One thing that seems clear, given the talk about agile development and operations, cloud computing, business and culture, our definition of devops continues to be accurate.

Another consistent part of devops that also emerged at PuppetConf last week was the way it tends to introduce additional stakeholders

Employee_Team +3 Vote Up -0Vote Down

Last week was a banner week for MySQL at OSCON. We had many MySQL developers meeting with the MySQL community, conducting technical sessions, leading BOF sessions, working the exhibit hall, and confirming Oracle's leadership in the technical evolution of MySQL.  The highlight of the week was the unveiling of even more 5.6 early access InnoDB and Replication features that are now available for early adopters to download, evaluate and shape via labs.mysql.com.  

InnoDB is one of MySQL's "crown jewels" and beginning in 5.5 is now the default storage engine.  The following 5.6 feature improvements are in direct response to community and customer feedback and requests.  The new 5.6 early access features include:


  • Full-text search

Tuning InnoDB Configuration
+2 Vote Up -0Vote Down
I had earlier written a post on tuning the MySQL server configuration which was more geared towards the MyISAM storage engine. While that is not because I didn't intend on ignoring InnoDB but because I had planned a whole post on tuning InnoDB related configuration. So this post is the post that I had planned, I have discussed the major configuration parameters in here that should help you out most of the times.

+3 Vote Up -1Vote Down
MySQL 5.5 has created a lot of hype and its not just hype, there are major performance enhancements not only in the MySQL server itself but in the newer InnoDB plugin shipped with MySQL 5.5. That's exactly the reason why I have myself upgraded to MySQL 5.5 (The server running this blog run MySQL 5.5).
