The latest from the MySQL community

Earlier today I did the presentation Memcached Meet Flash, the pluggable engine interface, and if you missed it you can download the slides. It is kind of fun to think back on the hackathon at the users conference the last year when Toru shared his ideas about a storage interface, followed by the interesting discussion I had with Matt during the OpenSolaris summit down in Santa Clara. I didn't know back then that I would present this at the users conference this year :-)

My brother came down for my presentation and took the following picture with his iPhone during the session:

If you have any questions regarding the slides, come look me …

Memcached is the de-facto distributed caching server used to scale many web2.0 sites today. With the requirement to support a very large number of users as sites grow, memcached aids scalability by effectively cutting down on MySQL traffic and improving response times.

Memcached is a very light-weight server but is known not to scale beyond 4-6 threads. Some scalability improvements have gone into the 1.3 release (still in beta). With the new Intel Nehalem based systems improved hyper-threading providing twice as much performance as current systems, we were curious to see how memcached would perform on these systems. So we ran some tests, the results of which are shown below :

memcached 1.3.2 does scale slightly better than 1.2.5 after 4 threads. However, both versions reach their …

Today I spoke with Farhan “Frank” Mashraqi, former Fotolog DBA, now working at a startup, NetEdge, working on social analytics. He’s talking about the two sessions he’s giving next week at the MySQL Conference & Expo 2009, as well as the benefits of being at the MySQL Conference & Expo.

He’s giving two talks:

1. Hadoop and MySQL: Friends with Benefits in where he will tell you about how you can combine data sets and queries, some of which run on Hadoop, and others which run on MySQL, but eventually probably end up in MySQL (he works on this cool stuff at NetEdge, the startup he’s currently attached to). …

I'm glad to announce the release of Memcached Functions for MySQL version 0.9. This version contains a couple bug fixes:

* Switched to using calloc() instead of malloc(), check for return value
* Changed memc_servers_set() to not create a new connection when one already exists, free first

Also added:

* memc_server_version()

mysql> select memc_server_version('127.0.0.1:11211')\G
*************************** 1. row ***************************
memc_server_version('127.0.0.1:11211'): Server: 127.0.0.1 (11211) version 1.2.6

I'm glad to get development moving along again. The book really took a ton of time, so now I can get this project moving along. Version 0.10 I'll be adding even more functionality. I'll get some ideas at the user's conference next week as well. One thing I need to get working properly is the ability to set a value in a specific …

... and this is my usual plea to those mysql/web/industrial folks to try out the latest code. Help us on our quest to scale the crap out of all of your stuff. :)

Find us on the mailing list, on #memcached on freenode, or on twitter as dormando, dlsspy, tmaesaka, and trondn. :) All others are fakers.

This week, I'm finishing up my book "Developing Web Applications using Perl, memcached, MySQL and Apache". I just finished up Chapter 1, which is the first chapter where I discuss several things such as how much things have changed in the last ten years with web development and Open Source in general. This lead me to write a small section about the future. I was pondering -- where are we going to be in ten years from now? What projects will be popular? This lead me even to a more specific question, and one that I would ask here: what is to become with the development of MySQL? What will be the official development branch of MySQL, and where is all the energy and excitement going to be around?

There is now one fork and one major branch of MySQL now that I will mention, both are exciting projects-- and neither of them is coming from official MySQL/Sun:
