Emit a recent change notification via Redis Pub/SubIf the feed URI contains a path component, it will be used to generate a channel name by stripping the leading slash and replacing any remaining slashes with '.'. If no path component is present, the channel is set to 'rc'. If the URI contains a query string, its parameters will be parsed as RedisConnectionPool options.

$wgRCFeeds['redis'] = array( 'formatter' => 'JSONRCFeedFormatter', 'uri' => "redis://127.0.0.1:6379/rc.$wgDBname", );
