This document discusses adding new databases to OpenStack Trove. It describes what Trove is, the databases it currently supports like MySQL, PostgreSQL and MongoDB. It explains how Trove works by provisioning databases on Nova instances using the Trove guest agent. The steps to add a new database are outlined as writing a spec, developing a guest agent, image elements and press release. An example code review for adding HBase is shown. Trove provides database as a service capabilities like backups, restores, resizing and high availability.

3. What is Trove?
The OpenStack Open Source Database as a Service Mission: To provide
scalable and reliable Cloud Database as a Service provisioning
functionality for both relational and non-relational database engines,
and to continue to improve its fully-featured and extensible open

8. What does it take to add a new database to Trove?
• Write a spec
• Implement a Guest Agent for the database
• Develop Image Elements (so you can build a guest image)
• Write a Press Release

12. We now illustrate Trove’s “backup” capability
• Trove “backup” is a mechanism to save all data in an instance onto
a Swift object
• Later you can launch a new instance with that data
• You can use this as a simple mechanism to dump and load data into
a new instance

13. What capabilities did are supported for HBase (now)?
• Create [and Delete]
• Restart
• Resize Instance and Disk
• Backup [and Create from Backup]
• In Standalone and Pseudo-Distributed Modes of Operation
