I’ve been spending a lot of time working on HandlerSocket these days, so I’ll be posting tidbits on this a bit more frequently than in the past. This first post is a quick one to help people get a test environment up and running quickly so they can do their functional testing. The title is [...]

I just received a confirmation that my presentation proposal for the MySQL user conference 2011 was accepted! The title for my proposal is MQL-to-SQL: a JSON-based Query Language for RDBMS Access from AJAX Applications, and it covers pretty much everything implied by the title.

As always, the Hyatt Regency Hotel in Santa Clara, California serves as the venue. The conference will be held from April 11-14. Except for the venue and period, I think this year's conference will bear few similarities to previous editions. Let me try and explain.

This year's theme is "MySQL, the ecosystem and …

Following the excellent post of Yoshinori about exceeding 750 000 qps with handler_socket,  i was curious to make my own opinion on the state of MySQL and MariaDB regarding simple primary key search.

Quoting  "Most of high scale web applications use MySQL + memcached. Many of them use also NoSQL like TokyoCabinet/Tyrant. In some cases people have dropped MySQL and have shifted to NoSQL. One of the biggest reasons for such a movement is that it is said that NoSQL performs better than MySQL for simple access patterns such as primary key lookups. Most of queries from web applications are simple so this seems like a reasonable decision"

I’m a big fan of NoSQL when it comes to remove useless work put on some …

The title says it all. If you don’t know what HandlerSocket is or why you would want to use it you need to reads Yoshinori Matsunobu’s blog post.

Lets get started.

Make sure you have these packages installed:

yum install git perl libtool gcc make openssl-devel gcc-c++ perl-DBI perl-DBD-MySQL.x86_64

If you haven’t already, install MariaDB and it’s source do that first and make sure it works. Look here http://askmonty.org/wiki/MariaDB:Download#Packages for the packages.

I’m using CentOS 5.5 x64 so I used:

wget http://ftp.osuosl.org/pub/mariadb/mariadb-5.2.4/kvm-rpm-centos5-amd64/rpms/MariaDB-client-5.2.4-94.el5.x86_64.rpm

Just a short note again on HandlerSocket developments: PHP bindings to the HandlerSocket client library have been spotted in the wild: http://code.google.com/p/php-handlersocket/ (I'd like to credit someone, but I have no idea who user "avuenta" is on Google Code. Is it you Dathan?)

I found this on Dathan Vance Pattishall's blog. I haven't personally had time to try it out yet as I'm still deep into my current project (of which I hope to blog in January).

"...php-handlersocket which is a PECL type version (C driver with exposure to PHP). It does the job but needs some work that I'm doing now."

Just wanted to highlight that Percona Server has now added HandlerSocket to its most recent release, being the first "MySQL fork/distribution" to ship it in easy to consume binary downloads.

HandlerSocket brings NoSQL to MySQL, and does so with a vengeance! It was developed at DeNa, by Akira Higuchi and is already used in production in their MySQL servers. The announcement on my former collague Yoshinori Matsunobu's blog flaunts a 7x performance improvement over the standard SQL interface in MySQL. The most astonishing part is that their MySQL is now faster than Memcached, even if the latter doesn't store anything to disk, so with this NoSQL-for-MySQL solution it makes sense to remove the caching layer completely! …
