Spryker provides flexible database connection configuration.

Single connection

The most probable use case and the Zed DB connection are good examples.

For this, open the environment config file (for example, APP_DIR/config/Shared/config_default-development_DE.php) and add the following parameters:

$config[PropelConstants::ZED_DB_USERNAME] = 'username';
$config[PropelConstants::ZED_DB_PASSWORD] = 'password';
$config[PropelConstants::ZED_DB_DATABASE] = 'database';
$config[PropelConstants::ZED_DB_HOST] = '127.0.0.1';
$config[PropelConstants::ZED_DB_PORT] = 3306;
$config[PropelConstants::ZED_DB_ENGINE] = $config[PropelConstants::ZED_DB_ENGINE_MYSQL];

By default, Spryker provides configuration for a single connection (two Zed and default, but with the same configuration). The configuration that you can find in APP_DIR/config/Shared/config_propel.php can look like the following:

$engine = $config[PropelConstants::ZED_DB_ENGINE];
$config[PropelConstants::PROPEL]['database']['connections']['default'] = $connections[$engine];
$config[PropelConstants::PROPEL]['database']['connections']['zed'] = $connections[$engine];

Multiple connections

Custom case which lets a project have more than one connections to different DBs. To define a new connection find a Propel configuration APP_DIR/config/Shared/config_propel.php and add the following (an example for Postgres):

$config[PropelConstants::PROPEL]['database']['connections']['additional_db_connection'] = [
'adapter' => PropelConfig::DB_ENGINE_PGSQL,
'dsn' => 'pgsql:host=127.0.0.1;port=5432;dbname=additional_db',
'user' => 'username',
'password' => 'password',
'settings' => [],
]

When a new connection is available, you can use it in your schema file.
