New Job announcment!
+0 Vote Up -0Vote Down

Some news about a change in my career path that I've been meaning to announce. I now have moved on from Lycos and now work for NorthScale Inc!

In parting Lycos, I'd like to thank them for the great challenges I had while there. I designed and developed, along with my team members in the web publishing and support from the OPs group, PHP offerings for Tripod users, a long-awaited feature that premium users can use to install numerous PHP applications. Also, with that was a great interface I developed for installing applications. It required some work on the applications themselves to make them as easy to install as possible (similar to APS). The other task while there was …

I'm pleased to announce the release of the Memcached Functions for MySQL, version 1.0.

This release contains several changes, per the ChangeLog:

1.0 Thursday, July 30, 2009 12:00:00 EST 2009
* Fixed issue of setting NULLs with user-defined variables (Thanks to
Jean-Jacques Moortgat at aol dot com !)
* Fixed issue of obtaining a NULL value FROM memcached
* All set functions now return 0 (failure) or 1 (success)
* Other cleanups
* More tests

Importantly, there was an issue that I blogged about several days ago where in the UDF API, if you pass a user-defined variable that is set to NULL to memc_set(), …

memcached Functions for MySQL now on launchpad
+0 Vote Up -0Vote Down

Hi all,

This is a quick post to let you know that the memcached functions for MySQL have been moved to Launchpad. The project page is:

I think this will help to get the project more exposure, as well as making it easier for people to contribute to the project. I've found Launchpad to be quite useful for managing projects and so decided to move the UDFs there.

I'm working on getting out another version soon. I just fixed a bug the deals with user-defined variables that were set to NULL causing the UDFs to crash the server. It was a bug in …

Analyze and optimize memcached usage with Maatkit
+5 Vote Up -0Vote Down

Ryan posted an article on the MySQL Performance Blog about how to use mk-query-digest to analyze and understand your memcached usage with the same techniques you use for MySQL query analysis. This is an idea that came to me during the 2009 MySQL Conference, while talking to our friends from Schooner, who sell a memcached appliance.

It suddenly struck me that the science of memcached performance is basically nonexistent, from the standpoint of developers and …

Maatkit Now Supports Memcached
+3 Vote Up -0Vote Down

Have you ever wondered how optimized your Memcached installation is? There is a common misconception that one doesn't have to think too deeply about Memcached performance, but that is not true. If your setup is inefficient, you could:

  • Burn Memory
  • Waste Network Round-Trips
  • Store Keys That Never Get Retrieved
  • Have a Low Cache Hit Ratio (i.e. query MySQL too much)
  • Suffer a fate too horrible to contemplate.

Percona does a lot of consulting around Memcached, so we try to take a quantitative, …

The commercialisation of Memcached
+0 Vote Up -0Vote Down

There has been a significant increase in interest in the Memcached, the open source distributed memory object-caching system, in recent months, as a number of vendors look to exploit its popularity in Web 2.0 and social networking environments.

Like Hadoop, which has become the focus of a number of commercial plays, it would appear that the time is right for commercialization of Memcached. But what is it, here did it come from, and what are the chances for vendors to rake in serious cash? Here are the details.

What is it?
Pronounced mem-cash-dee, Memcached was originally created by Danga Interactive (the …

multi-threaded memcached
+1 Vote Up -0Vote Down

I discovered while compiling Wafflegrid today that by default, the Ubuntu binaries for memcached are not-multithreaded.

Following the installation of memcached from apt-get and libmemcached I ran memslap for:

$ memslap -s localhost
    Threads connecting to servers 1
    Took 1.633 seconds to load data

$ memstat -s localhost
Listing 1 Server

Server: localhost (11211)
     pid: 23868
     uptime: 54
     time: 1244575816
     version: 1.2.2

OpenSolaris beats Linux on Memcached !
Employee +0 Vote Up -0Vote Down

Following on the heels of our memcached performance tests on SunFire X2270 ( Sun's Nehalem-based server) running OpenSolaris, we ran the same tests on the same server but this time on RHEL5. As mentioned in the post presenting the first memcached results, a 10GBE Intel Oplin card was used in order to achieve the high throughput rates possible with these servers. It turned out that using this card on linux involved a bit of work resulting in driver and kernel re-builds. …
