Data Cache Behavior for Propel2

A Propel ORM behavior that provide auto data caching to your model. Based on Propel 1.6 work of SNakano.

• support caching system APC, memcached and Redis (via DoctrineCache)
• auto caching and auto flush.

What's the difference with Query Cache Behavior

Query Cache Behavior is caching transformation of a query object (caching SQL code). This Behavior is caching the results of database. (caching result data)

Requirements

• PHP >= 5.3
• Propel >= 2.0.0
• DoctrineCacheFactory

Install

Composer

Add a dependency on thefuriouscoder/propel2-data-cache-behavior to your project's composer.json file.

{
    "require": {
        "thefuriouscoder/propel2-data-cache-behavior": "dev-master"
    }
}

Configuration

schema.xml

<table name="book">
  <column name="id" required="true" primaryKey="true" autoIncrement="true" type="INTEGER" />
  <column name="title" type="VARCHAR" required="true" primaryString="true" />
  <behavior name="data_cache">
    <parameter name="backend" value="apc" />     <!-- cache system. "apc" or "memcache", default "apc". (optional) -->
    <parameter name="lifetime" value="3600" />   <!-- cache expire time (second). default 3600 (optional) -->
    <parameter name="auto_cache" value="true" /> <!-- auto cache enable. default true (optional) -->
  </behavior>
</table>

Initialize the Cache Store.

Add the following configuration code to your project bootstraping file depending on the storage you are goinng to use.

Using Memcached (php5-memcached extension needed)

// configure memcached setting.
TFC\Cache\DoctrineCacheFactory::setOption(
    array(
        'storage'     => 'memcached',
        'prefix'      => 'rlyeh',
        'default_ttl' => 3600,
        'servers'     => array(
            array('server1', 11211, 20),
            array('server2', 11211, 80)
        )
    )
);

Using APC

// configure APC setting.
TFC\Cache\DoctrineCacheFactory::setOption(
    array(
        'storage'     => 'apc',
        'default_ttl' => 3600
    )
);

Using Redis

// configure Redis setting.
TFC\Cache\DoctrineCacheFactory::setOption(
    array(
        'storage'     => 'redis',
        'prefix'      => 'rlyeh',
        'host         => '127.0.0.1',
        'port'        => 6379,
        'default_ttl' => 3600
    )
);

Basic usage

$title = 'Cthulhu Mythos';
BookQuery::create()
    ->filterByTitle($title)
    ->findOne(); // from Database

BookQuery::create()
    ->filterByTitle($title)
    ->findOne(); // from caching system

Disable cache

$title = 'Cthulhu Mythos';
BookQuery::create()
    ->setCacheDisable()  // disable cache
    ->filterByTitle($title)
    ->findOne();

• setCacheEnable()
• setCacheDisable()
• isCacheEnable()
• setLifetime($ttl)

When cache delete?

$book = new Book;
$book->setId(1);
$book->setTitle("Cthulhu Myhtos");
$book->save();  // purge cache.

• expire cache lifetime.
• call save() method.
• call delete() method.
• call BookQuery::doDeleteAll() method.
• call BookQuery::purgeCache() method.

Manually delete cache.

$title = 'Cthulhu Mythos';
$query = BookQuery::create();
$book  = $query->filterByTitle($title)->findOne();
$cacheKey = $query->getCacheKey(); // get cache key.

BookPeer::cacheDelete($cacheKey);  // delete cache by key.
