Custom Datastore Class
 

It would be really nice if there was an option to include a custom datastore class PHP file so we could do just that (create custom datastores).

Something like this in the config.php file:
PHP Code:
$config['Datastore']['custom_file'] = 'class_datastore_custom.php';

And then in init.php* change this:
PHP Code:
if ($datastore_class != 'vB_Datastore')
{
require_once(DIR . '/includes/class_datastore.php');
}

to this:
PHP Code:
if ($datastore_class != 'vB_Datastore')
{
if ($config['Datastore']['custom_file'])
{
require_once(DIR . '/includes/' . $config['Datastore']['custom_file']);
} else {
require_once(DIR . '/includes/class_datastore.php');
}
}

That would give us infinite flexibility on datastore stuff... for example using the pooling/failover mechanism in memcached without bugging you guys to add it.

But there are other scenarios where I could think of why someone would want a totally custom datastore...

Maybe you want to do datastore writes to more than 1 memcached server* then handle memcached reads through a hardware load balancer. Or maybe you want to use something like APC* but the storing of keys happening on multiple web servers.

It just seems like a *very* easy addition to vBulletin that would allow bigger forums to develop their own custom datastores without the need to hack on PHP files.
