Preface
Database-as-a-Service (DBaaS) enables users to conveniently utilize a relational or non-relational database in their OpenStack environment without having to worry about the administrative tasks such as deployment, configuration, or backups. This functionality is provided by the trove component, which provisions and manages guest database images.
DEPRECATION NOTICE: Beginning in Red Hat OpenStack Platform 10, the OpenStack Trove service will no longer be included in the Red Hat OpenStack Platform distribution. We are working with a trusted partner to provide our customers with a production ready DBaaS service. Please contact your sales account manager to learn more about this option.
DBaaS comprises several services:
- Guest Agent service, running on guest instances and managing the datastore; this includes bringing a new datastore online and performing database operations.
- Task Manager service, which provisions, manages, and performs operations on instances.
-
API service, which provides a RESTful API and forwards API requests to the guest agent or task manager. Command-line interface to the DBaaS API is provided by the
troveclient, which is part of thepython-troveclientpackage. - Conductor service, running on the host and listening for messages from guest instances to pass to the host; for example, status updates.
The following database platforms are supported:
- MySQL 5.5 and 5.6
- MariaDB 5.5 and 10
The OpenStack Database-as-a-Service is available in this release as a Technology Preview, and therefore is not fully supported by Red Hat. It should only be used for testing, and should not be deployed in a production environment. For more information about Technology Preview features, see Scope of Coverage Details.
