6. Specs for Trove
• Specifying specs on the wiki was getting cumbersome
• Hard to do reviews
• Hard to get feedback from ops, and users
• Hard to track changes
• In Kilo Trove moved to doing specs using gerrit
• http://specs.openstack.org/openstack/trove-specs
• https://review.openstack.org/#/q/status:open+project:openstack/trove-
specs,n,z

7. Improving Replication
• Horizon Support for Replication
• Create instance as replica
• Detach replica from replication source
• Support for GTID based replication for MySQL
• Support for various methods of failover
• detach-instance
• eject-replica-source

8. Datastore Improvements
• Added implementations of new datastores
• Single instance CouchDB
• Single instance IBM DB/2
• Support for HP Vertica
• Single instance support
• Support for Vertica Clusters for community (3 nodes)

9. Paying off Technical Debt
• Removal of 3rd Party external “Deprecated Trove CI”
• All testing and CI now run under OpenStack Infra
• Functional / int-tests run in devstack-vm-gate
environment
• Cleaning out deprecated oslo-incubator code.
• Switch to oslo.messaging for RPC

10. Liberty

11. Datastore Improvements - MongoDB
• Support for backup and restore for MongoDB
• Using mongodump as initial strategy
• Support for MongoDB configuration groups

• Galera cluster using Percona XtraDB Cluster
• Support for Redis clusters
• Based on newly released Redis 3.02

14. Flavors Per Datastore
• Limit certain datastores to only run on certain flavors
• Increasingly important as Trove supports more datastores
• E.g. MySQL can run fine on a small instance with 2G disk,
but Vertica or MongoDB cannot

15. Horizon Improvements
• Ability to deploy Trove Clusters through Horizon
• User / Database management through Horizon
•Including root user management
• Configuration groups in Horizon

16. Simplifying Operations
• Best practices deploying Trove in production

• Ability to deploy Trove instances in a “Service Tenant”

17. Other Improvements
• Exposing datastore logs to users through the Trove API
• Support for management APIs in python-troveclient
• Extending guest heartbeats to monitor datastores
• Metadata support for Trove instances

18. Your Idea Here!
• Growing community of contributors
