class airflow.models.connection.Connection(conn_id: Optional[str] = None, conn_type: Optional[str] = None, description: Optional[str] = None, host: Optional[str] = None, login: Optional[str] = None, password: Optional[str] = None, schema: Optional[str] = None, port: Optional[int] = None, extra: Optional[Union[str, dict]] = None, uri: Optional[str] = None)[source]

Bases: airflow.models.base.Base, airflow.utils.log.logging_mixin.LoggingMixin

Placeholder to store information about different database instances connection information. The idea here is that scripts use references to database instances (conn_id) instead of hard coding hostname, logins and passwords when using operators or hooks.
