Trove/backup-metadata

Description

This blueprint will add the datastore and version to the backups api response.

Blueprint: https://blueprints.launchpad.net/trove/+spec/backup-metadata

Justification/Benefits

• This will allow filtering the backups list by datastore type (and version?)
• Eventually allow the api to restrict which datastore a backup could be restored to. (mysql -> mysql) (redis -> redis)

Impacts

Configuration

None

Database

• The backup table will need to have a foreign key to the Datastore Version table.
• This will require a migration to add the foreign key to all existing records

Public API

• This will add the datastore type and version to the API Response
• This will also add the ability to filter the backup list by datastore

CLI interface

• This will add a single param to backup-list command '--datastore' to filter the list by that datastore

New backup list Response:
