As a followup to my previous post on installing HandlerSocket on CentOS 5 + Percona-Server 5.1, I’ve been asked to provide an updated HOWTO for RHEL 6 + Percona-Server 5.5. Although very similar to the original steps, there are some new traps (RHEL 6 comes with SELinux enabled) and there are some new ec2 gotchas! [...]

A post on the HandlerSocket-dev mailing list the other day got me thinking about the performance of MySQL’s IN() construct versus HandlerSocket’s execute_multi. So I started a little test, using MySQL 5.5 + HandlerSocket’s latest commits: mysql> CREATE TABLE `test`.`t1` ( -> `id` int unsigned NOT NULL AUTO_INCREMENT, -> `val` char(32) NOT NULL, -> PRIMARY [...]

I’ve presented at two different venues about HandlerSocket recently and the number one question that always arises is:

Why hasn’t HandlerSocket become more popular than it is?

Considering how fast and awesome HandlerSocket is, it’s not seeing as rapid adoption as some might expect. I theorize that there are five reasons for this:

Bugs, Bugs, Bugs

Up until the beginning of the year, HandlerSocket had a couple of bugs that a lot of people considered deal-breakers, and it’s not widely known that these issues have been fixed.

HandlerSocket has really generated a lot of interest because of the dual promises of ease-of-use and blazing-fast performance. The performance comes from eliminating CPU consumption. Akira Higuchi’s HandlerSocket presentation from a couple of months back had some really good profile results for libmysql versus libhsclient (starting at slide 15). Somebody in the audience at Percona Live asked about the profile results when using prepared statements and I’m just getting around to publishing the numbers now; I’ll reproduce the original numbers here, for reference:

UPDATE 2011-03-15 12:50 Pacific – This post may already be out of date, am testing with a fresh snapshot of the source and will update accordingly. (Thanks, Andy)

Several weeks ago at Percona Live 2011, I presented on HandlerSocket. Due to time constraints, I had to omit some more in-depth discussions in favor of being able to present a broad overview. One of those discussions was about how, exactly, HandlerSocket does not play nicely with auto increment columns. So I wanted to take the time here to show how they behave together versus how we might expect.

Let’s take, for example, a standard setup using a standard SQL_MODE (not using anything like

I’ve written some new Nagios checks for HandlerSocket. check_handlersocket is a part of http://code.google.com/p/check-mysql-all/, and is meant to be called locally on the HandlerSocket server (usually via NRPE), but the perl-Net-HandlerSocket module must be installed.

HandlerSocket is great, but don't compare it to Memcache just yet.

(edit) mysql, memcache, handlersocket
The HandlerSocket plugin for MySQL currently lacks atomic operations .  It is impossible to implement counters (increment/decrement value) or REPLACE functionality with the current implementation. 

It currently exceeds the performance of Memcache for get/set operations, but I want to see how fast it is once atomic operations are implemented. Until then, I don't think it is a serious contender for replacing Memcache for the cache layer in a complex environment.

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.

 login as root

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

We're publishing a new Strata Gem each day all the way through to December 24. Yesterday's Gem: What your inbox knows.

The trend for NoSQL stores such as memcache for fast key-value storage should give us pause for thought: what have regular database vendors been doing all this time? An important new project, HandlerSocket, seeks to leverage MySQL's raw speed for key-value storage.

NoSQL databases offer fast key-value storage for use in backing web applications, but years of work on regular relational

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).

UPDATE: Oracle officially released memcached daemon plugin that talks with InnoDB. I'm glad to see that NoSQL+MySQL has become an official solution. It's still preview release but will be very promising. Let's try it to make it better!

  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.
  Like many other high scale web sites, we at DeNA(*) had
