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
• More information at:
