class airflow.models.connection.Connection(conn_id=None, conn_type=None, description=None, host=None, login=None, password=None, schema=None, port=None, extra=None, uri=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.
