Details

Make all database connections secretly go to localhost. Fool the load balancer thinking there is an arbitrarily large cluster of servers to connect to. Nützlich für Debugging.

For example you might have a configuration like:

$wgLBFactoryConf = array(
 'class' => 'LBFactoryMulti',
 'sectionsByDB' => array(
    'wikidb' => 's1',
 ),
 'sectionLoads' => array(
    's1' => array(
        'localhost'  => 0,
        'somewhereElse'  => 0,
        'place20'  => 300,
        'place21'  => 300,
        'place3'  => 400,
        'place31'  => 400,
    ),
 ),
 'serverTemplate' => array(
    'dbname'      => $wgDBname,
    'user'          => $wgDBuser,
    'password'      => $wgDBpassword,
    'type'          => 'mysql',
    'flags'          => ( $wgDebugDumpSql ? DBO_DEBUG : 0 ) | DBO_DEFAULT,
    'max lag'      => 30,
    'fakeSlaveLag' => 1, // Needed since the "slaves" aren't really slaves
 ),
);
$wgAllDBsAreLocalhost = true;

Which would cause MediaWiki to behave like it had 6 db servers (1 master + 5 slaves), when really you just have the 1 DB on localhost.
