Project codename:



A control plane and data plane for deploying and operating relational (SQL) and non-relational (NoSQL) database management systems on OpenStack.

Detailed Description:

Reddwarf is Database as a Service for Openstack. It's designed to run entirely on OpenStack, with the goal of allowing users to quickly and easily utilize the features of a database without the burden of handling complex administrative tasks. Cloud users and database administrators can provision and manage multiple database instances as needed. The service focuses on providing database resource isolation while automating complex administrative tasks including deployment, configuration, patching, backups, restores as well as horizontal and vertical scaling. While initially focused on MySQL, the future of Reddwarf will support multiple database technologies, including relational (SQL) and non-relational (NoSQL) technologies such as Redis, MongoDB, MariaDB, PostgreSQL, etc.. The long-term vision for Reddwarf is to provide a framework to control any persistant database management system.

Today, Reddwarf is a consumer of OpenStack. It is built on and leverages core OpenStack infrastructure services. It allows a service provider the flexibility of deployment and configuration of the core OpenStack components, and uses those components as the building blocks of its service. This includes Keystone for auth, Nova for instance creation, Cinder for volume support, Glance for images, Swift to store backups, and networking. In the future, we hope to eventually consume Ceilometer for metrics and Heat for initial image creation/orchestration, and potentially bare metal to spin up Reddwarf instances for the infrastructure database(s) within a OpenStack on OpenStack install.

With the recent adoption of Heat as an integrated project in OpenStack, many will question the need for a defined database service as Heat can orchestrate the setup of complex database clusters as well as handle basic lifecycle management of the database cluster. However, this is only one piece of a managing a database at scale. Reddwarf is layer above Heat, and as the project evolves, we will be able to leverage Heat to set up the database management system, which fits perfectly into our goal of leveraging core OpenStack services. The main differentiator for persistent datastores is that they require tightly integrated and specific operations such as controls to efficiently execute/schedule backups, restore a database to a specific point in time, configuration and optimization of the database, maintenance and management of data replication (masters and slaves) for horizontal scalability, and other database management tasks. A persistent datastore, clustered or not, is not simply a fire and forget resource. It needs constant monitoring and maintenance and we want to use this as the differentiator between Reddwarf and a service for orchestrating the creation of OpenStack resources. However, as Heat continues to evolve, and some basic lifecycle management tasks can be executed through it, we will have the option to leverage those operations.

Basic roadmap for the project:

Currently, Reddwarf can deploy multiple MySQL implementations, including core MySQL and Percona MySQL. The API continues to evolve through the addition of new features, but as it stands is very stable in its implementation for the basic tasks of creating and maintaining a single instance database deployment. The system is built such that multiple technologies can be leveraged, from the datastore implementation itself, to the tools used to keep maintenance ongoing. For instance, the backup feature, currently in progress, allows the cloud deployer to choose mysqldump or xtrabackup to backup the datastore. Over time, this will be expanded to support storage level snapshotting for larger volume installations.

From a datastore perspective, Reddwarf's functionality currently is the ability to spin up secured MySQL databases, create/destroy schemas and users, and enable a root user. From a openstack project perspective, Reddwarf also has quota and limit support and consumes Oslo to build out the architecture of the API.

Reddwarf has a healthy backlog of features such as database configuration control, manual backups and restores, and notifications. Others that are not yet started include scheduled backups, point in time database restores, API types/versions, full featured user modification, and replication for horizontal database scalability. The current roadmap can be viewed as blueprints on launchpad and will be continually updated as new feature requests are created. We will be working to add support for NoSQL soon.

There are also many housekeeping blueprints to maintain parity with other OpenStack projects. Reddwarf has strived to keep in line with the ecosystem, but there are some things that are necessary, such as completing integration with devstack. As it stands, reddwarf is integrated as much as possible today, and uses local.sh to instrument the reddwarf infrastructure. It also currently uses vm-gating and runs functional tests on every review.

Location of project source code:

Reddwarf operates like any other openstack project. Blueprints are registered and approved in the same fashion as the other projects, release cycles are followed, and code is gated through unit tests and functional tests. The codebase is in stackforge. Reviews are in openstack gerrit.

Programming language, required technology dependencies:

Python. pypi dependencies are listed in pip-requires and test-requires.

Is project currently open sourced? What license?:

Yes. Apache 2.0.


Level of maturity of software and team:

The team has followed the openstack ecosystem for a long time. They are well versed in understanding the ecosystem and follow it as closely as possible. Weekly meetings are held, a presence is always in irc, reviews are thoroughly picked through, and they hold a high standard for all code that lands in master. All features require unit and functional tests, and gating is done on these through OpenStack jenkins and a external jenkins for said functional tests. The software is run in a production OpenStack deployment at Rackspace on hundreds of nodes across multiple datacenters encompassing thousands of active database deployments.

Proposed project technical lead and qualifications:

Michael Basnight (hub_cap on irc). Michael has lead the project since its inception at rackspace. He was the lead of the internal project, but has shifted his role within Rackspace to be fully dedicated to lead the public project. He is focused on the quality of the API, infrastructure, and testability of the project. He follows the openstack community closely and has contributed greatly to the project. He currently manages blueprints, runs the weekly meetings, and evangelizes reddwarf in the community. He has spoken at many of the OpenStack conferences and has attended almost all of the conferences since reddwarf began within Rackspace.

Community vendors We have had an uptick in interest from the community with respect to clustering and replication. Percona, Continuent (Tungsten) and CoderShip (Galera) are interested in helping us. Also SkySQL is interested in helping w/ Maria integration and they have a product similar to RedDwarf so they are interested in contributing to our product as well.

Infrastructure requirements (testing, etc):

Reddwarf has built its own testing environment. Its currently run as a gating job within by jenkins. Tox runs pep8 and unit tests on each commit through openstack gerrit. The reddwarf developers understand that, over time, they will adopt the openstack testing frameworks for all new functional tests. The core of reddwarf is run on openstack and installed within devstack. Reddwarf-integration, a project on stackforge, controls the installation and setup of reddwarf for development and testing. Tests are run in a openstack/kvm environment.
