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
Kilo Overview
• 266 Commits from 71 different contributors
• ~22 BPs and ~150 bugs fixed
• ~3000 code reviews with 45956 total Lines of Code changed.
• More details:• https://launchpad.net/trove/juno• http://stackalytics.com/?release=juno&module=trove-group
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/tr

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
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)
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• Updates to latest oslo-incubator code
Datastore Improvements - MongoDB
• Support for backup and restore for MongoDB
• Using mongodump as initial strategy
• Support for MongoDB configuration groups
• Basic user and database management
Datastore Improvements - Redis
• Update to latest Redis 3.02
• Support for backup and restore for Redis
• Support for Redis configuration groups.
Improvements to Clustering
• Support for synchronous multi-master MySQL clusters
• Galera cluster using Percona XtraDB Cluster
• Support for Redis clusters
• Based on newly released Redis 3.02
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
Horizon Improvements
• Ability to deploy Trove Clusters through Horizon
• User / Database management through Horizon
• Including root user management
• Configuration groups in Horizon
Simplifying Operations
• Best practices deploying Trove in production
• Based on feedback from the Mailing List and Summit
• New operations manual tackling deployment issues
• Ability to deploy Trove instances in a “Service Tenant”
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
