MySQL HandlerSocket under Ubuntu

Starting with the great work of Yoshinori-san Using MySQL as a NoSQL – A story for exceeding 750,000 qps on a commodity server and Golan Zakai who posted Installing Dena’s HandlerSocket NoSQL plugin for MySQL on Centos I configured and tested HandlerSocket under Ubuntu 10.04 64bit.

NOTE: This machine already compiles MySQL and Drizzle. You should refer to appropriate source compile instructions for necessary dependencies.

Now all built, it’s as simple as the following to install:

However, I found it not actually running even after restarting MySQL. You need the following configuration

cd ${DIR}/mysql5152
echo "[mysqld]
plugin-load=handlersocket.so
loose_handlersocket_port = 9998 # the port number to bind to (for read requests)
loose_handlersocket_port_wr = 9999 # the port number to bind to (for write requests)
loose_handlersocket_threads = 16 # the number of worker threads (for read requests)
loose_handlersocket_threads_wr = 1 # the number of worker threads (for write requests)" >> my.cnf

After restarting you get the following confirmation.

My Test Data

USE test
CREATE TABLE user (
  user_id INT UNSIGNED NOT NULL,
  name VARCHAR(50) NOT NULL,
  email VARCHAR(255) NOT NULL,
  created TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY(user_id)
) ENGINE=InnoDB; 

INSERT INTO user (user_id,name, email) VALUES
(100,'Mickey Mouse','mickey@acme.inc'),
(101,'Marvin the Martian','mars@warnerbros.inc'),
(102,'Spiderman','spidy@marvelcomics.inc');

SELECT user_id,name,email FROM user WHERE user_id=101;
+---------+--------------------+---------------------+
| user_id | name               | email               |
+---------+--------------------+---------------------+
|     101 | Marvin the Martian | mars@warnerbros.inc |
+---------+--------------------+---------------------+

My test retrieval program is basically unchanged from the original post.

$ cat retrieve.pl
#!/usr/bin/perl

use strict;
use warnings;
use Net::HandlerSocket;

#1. establishing a connection
my $args = { host => '10.0.0.6', port => 9998 };
my $hs = new Net::HandlerSocket($args);

#2. initializing an index so that we can use in main logics.
 # MySQL tables will be opened here (if not opened)
my $res = $hs->open_index(0, 'test', 'user', 'PRIMARY',
    'name,email,created');
die $hs->get_error() if $res != 0;

#3. main logic
 #fetching rows by id
 #execute_single (index id, cond, cond value, max rows, offset)
$res = $hs->execute_single(0, '=', [ '101' ], 1, 0);
die $hs->get_error() if $res->[0] != 0;
shift(@$res);
for (my $row = 0; $row < 1; ++$row) {
  my $user_name= $res->[$row + 0];
  my $user_email= $res->[$row + 1];
  my $created= $res->[$row + 2];
  print "$user_name\t$user_email\t$created\n";
}

#4. closing the connection
$hs->close();

If your HandlerSocket is not running you will see:

$ perl retrieve.pl
FATAL_EXIT: getaddrinfo failed: ip_to_remote_host:9998
$ telnet 10.0.0.6 9998
Trying 10.0.0.6...
telnet: Unable to connect to remote host: Connection refused

When working

$ telnet 10.0.0.6 9998
Trying 10.0.0.6...
Connected to 10.0.0.6.
Escape character is '^]'.
P	0	test	user	PRIMARY	name,email,created

$ perl retrieve.pl
Marvin the Martian	mars@warnerbros.inc	2010-11-05 13:11:34

Again, great work by Yoshinori-san to have this code as production deployable. Now to run some real benchmarks.

    two little typos:
    cd $DIR}/mysql5152
    -> cd${DIR}
    echo ” ..” > my.cnf
    here Im not sure if it is ok/recommended to truncate my.cnf first.

  3. Ronald Bradford says:

    Thanks.

    For a tar install of MySQL, there is no my.cnf in this directory so truncation would not be an issue, and I don’t want multiple section headers. however for completeness I did make it an append rather then truncation as that also works.

  4. Piglei says:

    Now to run some real benchmarks.
    =====================
    Could you give me any test results about this plugin?
    I installed this plugin on mysql5.1.41 too, it works.
    but it’s not that good as the author said(75000qps..), I uses python’s client.

    All the links seem to be 404, can you update them ?
    So far the best/detailed description ive found to get handlersocket setup…
