3. Trove Highlights
• Trove is the OpenStack Database as a Service project
– Easily provision and manage the life-cycle of a database in the cloud
– Supports both relational databases (like mySQL and PostgreSQL)
– And non-relational engines (like MongoDB, Cassandra, and Couchbase)
• The data-plane and the management-plane
– Trove stays on the management-plane
– Rarely on the data-plane
– Backup and restore being the exception

12. Kilo Specs
• In Juno
– Trove did its blueprints in Wikipages, but had problems with reviews
– Not good for annotation and users could not easily track changes
– It was also difficult to get feedback
• Trove will be moving back towards the old specs process
– Move back to doing specs using Gerrit.
– Working well so far (see the trove-specs repository)

13. More Datastore Improvements
• Incremental improvements for existing datastores
• Introduce implementations of datastores for CouchDB and Vertica
• Add an API to fetch database logs from guest instances
– If something goes wrong, they need a programmatic way to figure out
the problem
