Constructor & Destructor Documentation

◆ __construct()

MediaWiki\JobQueue\JobQueueDB::__construct ( array $params )

protected

Additional parameters include:

server : Server configuration array for Database::factory. Overrides "cluster".
cluster : The name of an external cluster registered via LBFactory. If not specified, the primary DB cluster for the wiki will be used. This can be overridden with a custom cluster so that DB handles will be retrieved via LBFactory::getExternalLB() and getConnection().

Reimplemented from MediaWiki\JobQueue\JobQueue.

Definition at line 75 of file JobQueueDB.php.
