Magento MySQL AsyncSave

DEPRECATED Magento implementation of http://php.net/manual/en/mysqli.query.php to use MYSQLI_ASYNC for inserts and updates.

Latest commit and statistics from GitHub:

Magento implementation of http://au1.php.net/manual/en/mysqli.query.php to use MYSQLI_ASYNC for inserts and updates.

Fire and forget.

This fails because Magento uses too many connections and one async query can only use one connection. IMHO setting the max connection variable to a higher value cannot be a solution. The guy here http://sysmagazine.com/posts/155377/ stuck in the same situation …

Real DML async queries with one connection are not possible :-(

API

Please only instantiate this resource via singleton.

Available methods

$this save(Mage_Core_Model_Abstract $object, array $_fieldsForUpdate = null)

With its _beforeSave and _afterSave methods if you want extend the Async resource class.

$this delete(Mage_Core_Model_Abstract $object)

With its _beforeDelete and _afterDelete methods if you want extend the Async resource class.

For both methods save() and delete() the provided $object must have a valid resource object.

$this setSerializableFields(array $serializableFields)

raw_query($sql, array $bind = null)

null|bool|mysqli_result getLastAsyncResult()

Examples

$collection = Mage::getModel('catalog/product')->getCollection();
foreach($collection as $product){
    $product->setName(...)->setPrice(...);
    Mage::getResourceSingleton('schumacherfm_asyncsave/async')->save($product);
}
$sql = $select->insertFromSelect($this->getFlatTableName($storeId), $fieldList);
Mage::getResourceSingleton('schumacherfm_asyncsave/async')->raw_query($sql, $bind);

Disadvantage / Risks
