API / $connector
Through the connector it is possible to access configured connection objects. A connection is i.e. a MYSQL connection which can be configured at the admin panel. Inside an action it is possible to access this connection through this class. Which objects is returned depends on the connection type i.e. the MYSQL connection returns a Doctrine DBAL Connection instance and the HTTP connection returns a Guzzle instance. There are already many adapters available which allow many different kind of services i.e. ElasticSearch, MongoDB, AMQP, etc.
|getConnection||Returns an arbitrary connection to a remote service. It is recommended to use the connection name but you can also use the actual database id of the connection|
