The document outlines enhancements to the Trove database service from the Icehouse to Juno releases of OpenStack. Key additions in Juno include support for asynchronous MySQL replication, integration with Neutron networking, expanded configuration groups, additional datastore support like PostgreSQL and Vertica, cross-region backups, and improved testing. The goal is to provide a scalable, reliable database as a service with a fully-featured open source framework.

2. Trove Icehouse to Juno

3. 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 source
framework.
Mission Statement

4. Icehouse

5. Non Relational DB Types
• Support for datastore type, and version
• Support for
• Cassandra
• MongoDB
• Redis
• Couchbase
• Currently only supports single instances

6. DNS Support
• Integration with Designate
• Provision Trove instances with DNS name

7. Configuration Groups
• Support for user defined configuration settings
• Supports defining certain mysql (my.cnf) settings
• Allow grouping settings, and targeting groups to instances

8. Heat Integration
• Support for configuration based “heat” mode
• Default heat templates for each datastore provided
• Supports user-defined custom heat templates per datastore

9. Incremental Backup / Restore
• No longer necessary to perform full backups every time
• Specify a “parent” backup in API call
• Leverages xtrabackup to perform incremental backup

10. Trove Conductor
• New component added to Trove Control Plane
• Guest no longer needs direct connection to the Trove DB
• Uses RPC messages to communicate with guest
• Supports heartbeat messages, and Backup / Restore checks

11. Miscellaneous
• Goodbye XML API
• Support for Tempest API tests
• Trove Deployment Guide

12. Juno

• Configuration Groups Enhancements
• Allow users to add descriptions to groups
• Better schema-based validation for values

16. Datastore Improvements
• Associate flavors with datastores
• Support for other datastores
• PostgreSQL
• Vertica
• Ability to view datastore log files

17. Enhancements to Backups
• Cross-region availability of backups
• Backup/restore for non-mysql datastores
• Cassandra
• Couchbase

18. Testing Enhancements
