Dependencies

+

Before deploying MemcacheQ, make sure that following packages have been installed:

+
+

Berkeley DB 4.7 or later

+

Download from <http://www.oracle.com/database/berkeley-db/db/index.html>

+

How to install BerkekeyDB:

+
+$tar xvzf db-4.7.25.tar.gz
+$cd db-4.7.25/
+$cd build_unix/
+$../dist/configure
+$make
+$sudo make install
+
+
+
+

libevent 1.4.x or later

+

Download from <http://monkey.org/~provos/libevent/>

+

How to install libevent:

+
+$tar xvzf libevent-1.4.x-stable.tar.gz
+$cd libevent-1.4.x-stable
+$./configure
+$make
+$sudo make install
+
+

On a linux, load .so file by add two line in /etc/ld.so.conf:

+
+/usr/local/lib
+/usr/local/BerkeleyDB.4.7/lib
+
+

Then, run 'ldconfig'.

+
+
+
+

Building MemcacheQ

+

On a *nix, just following:

+
+$tar xvzf memcacheq-0.1.x.tar.gz
+$cd memcacheq-0.1.x
+$./configure --enable-threads
+$make
+$sudo make install
+
+
+
+

Start the daemon

+

For example:

+
+memcacheq -d -r -H /data1/memcacheq -N -v -L 1024 -B 1024 > /data1/mq_error.log 2>&1
+
+

Notice: Because MemcacheQ is using fixed-length storage, so you should use '-B' option to specify the max length of your message. Default is 1024 bytes. Any message that shorter than the length you specified will be padded with '0x20', the space character. A message includes following bytes:

+
+<your queue name bytes> + <message metadata(9 ~ 20+ bytes)> + <your message body bytes>
+
+

use "-h" option to see more configures.

+

Have fun :)

MemcacheQ - Simple Queue Service over Memcache

+ +
+

Features

+
    +
  • damn simple
    • +
  • very fast
    • +
  • multiple queue
    • +
  • concurrent well
    • +
  • memcache protocol compatible
    • +
+
+
+

Getting Started

+ +
+

Installation

+

See: <http://memcachedb.org/memcacheq/INSTALL.html>

+

Please take a look at 'ChangLog' file in the distribution, see what's new.

+
+
+

Commands

+

Only two commands are used to operate the queue:

+

Append a message to the tail of queue:

+
+set <queue name> <flags> 0 <message_len>\r\n
+<put your message body here>\r\n
+STORED\r\n
+
+

Note: MQ will create a new queue automatically if your queue is not existed. The original 'expire time' field is ignored by server.

+

Consume a message from the head of queue:

+
+get <queue name>\r\n
+VALUE <queue name> <flags> <message_len>\r\n
+<your message body will come here>\r\n
+END\r\n
+
+
+
+

Examples

+

Assuming you are using PHP memcache<http://www.php.net/memcache>:

+
+<?php
+/* connect to memcached server */
+$memcache_obj = memcache_connect('memcacheq_host', 21201);
+
+/* append a message to queue */
+memcache_set($memcache_obj, 'demoqueue1', 'message body here', 0, 0);
+
+/* consume a message from 'demoqueue1' */
+memcache_get($memcache_obj, 'demoqueue1');
+
+memcache_close($memcache_obj);
+?>
+
+
+
+
+

Limitation

+

The message body is stored in Berkeley DB with fixed length. Any message that is shorter than the declared length will automatically be padded with space character (0x20 in the ASCII character set).

+

In Berkeley DB, as the official document refers,

+

"For the Queue access method, the record length must be enough smaller than the database's page size that at least one record plus the database page's metadata information can fit on each database page."

+

"The minimum page size is 512 bytes, the maximum page size is 64K bytes, and the page size must be a power-of-two."

+

So we have a limit on the message body size with a max of a bit less than 64K.

+
+
+

Other tips

+

use 'stats queue' to see your current queues:

+
+$ telnet 127.0.0.1 22201
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+stats queue
+STAT test1
+STAT test2
+STAT test3
+STAT test4
+END
+
+

delete a queue:

+
+$ telnet 127.0.0.1 22201
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+delete test1
+DELETED
+
+

'db_stat' a queue to see how many records now in:

+
+$ cd <your queue dir>
+$ /usr/local/BerkeleyDB.4.7/bin/db_stat -d test1
+Mon Sep 22 20:25:56 2008      Local time
+42253   Queue magic number
+4       Queue version number
+1024    Fixed-length record size
+0x20    Fixed-length record pad
+4096    Underlying database page size
+131072  Underlying database extent size
+100000  Number of records in the database
+33334   Number of database pages
+2048    Number of bytes free in database pages (99% ff)
+1       First undeleted record
+100001  Next available record number
+
+
+
+
