BerylliumCacheBundle for Symfony2

It's memcache. You've seen it before. Now it's injectable to the DIC, and you don't have to write all this junk yourself. And it should also work with Amazon ElasticCache, as well as the MySQL Memcache Interface (new in MySQL 5.6)., _(*1)

Another advantage over just using a raw memcache object is that BCB probes servers before adding them to the pool - if a server is down, your site won't be gravely impacted by the Memcache class waiting and waiting and waiting for a response., _(*2)

The groundwork is also laid out for building alternate cache interfaces quickly - such as APC caching, or your own home-rolled filesystem cache., _(*3)

Configuration

Step 1: Fetching

If you are using composer, you probably only need to add this to your composer.json file:, _(*4)

"require": {
  "Beryllium/CacheBundle": "dev-master"
},

If you aren't using composer, add this to your deps file:, _(*5)

[BerylliumCacheBundle]
    git=http://github.com/beryllium/CacheBundle.git
    target=/bundles/Beryllium/CacheBundle

And then run the update vendors script:, _(*6)

bin/vendors install

Step 2: Configure autoload.php

If you aren't using Composer, register the namespace like so:, _(*7)

# app/autoload.php

<?php

$loader->registerNamespaces( array(
  //...
  'Beryllium' => __DIR__.'/../vendor/bundles',
  ) );

Step 3: Configure the AppKernel

Add it to your AppKernel:, _(*8)

# app/AppKernel.php

<?php

    $bundles = array(
        //...
        new Beryllium\CacheBundle\BerylliumCacheBundle(),
    );

Configure your server list in parameters.ini:, _(*9)

beryllium_cache.client.servers["127.0.0.1"] = 11211

Or for parameters.yml:, _(*10)

parameters:
    ...
    beryllium_cache.client.servers: { "localhost": 11211 }

If you want to change the default cache TTL value (300 seconds) you can add this to your parameters.yml:, _(*11)

parameters:
    ...
    beryllium_cache.default_ttl: 86400

If you plan on using local UNIX sockets, GitHub user gierschv has contributed the ability to do this:, _(*12)

beryllium_cache.client.servers["unix:///tmp/mc.sock"]=""

And then you should be good to go:, _(*13)

$this->get( 'beryllium_cache' )->set( 'key', 'value', $ttl );
$this->get( 'beryllium_cache' )->get( 'key' );

You might want to set up a service alias, since "$this->get( 'beryllium_cache' )" might be a bit long., _(*14)

The Command Line

For a command line report of CacheClient statistics (assuming the cache client has a ->getStats method, which is not an interface requirement), you can do the following:, _(*15)

app/console cacheclient:stats

Example Output:, _(*16)

Servers found: 1

Host:    127.0.0.1:11211
    Usage: 0% (0.01MB of 64MB)
    Uptime: 344976 seconds (3 days, 23 hours, 49 minutes, 36 seconds)
    Open Connections: 15
    Hits: 26
    Misses: 29
    Helpfulness: 47.27%

Or, for extended information (the raw stats array), you can run with debugging enabled:, _(*17)
