Trove/datastore-visibility

Description

This blueprint suggests adding a visibility attribute to the datastore versions. This enables the datastore to be still active, but not visible to the users.

Blueprint: https://blueprints.launchpad.net/trove/+spec/datastore-visibility

Justification/Benefits

There might be some datastores, which the deployers require to be active but not visible to customers in production environment. This visibility flag ensures that only the datastore versions which have been marked as public are visible in the list. Example use case: Say we want to have an active datastore A in production and not expose it to customers yet. The visibility flag will ensure it is visible on the datastore list call only to admins.

FAQ: (1) Why is the flag a string visibility vs a boolean is_public? In glance, we have is_public as a boolean flag. But as we started introducing new features like image sharing, we realized that having a boolean made it harder to add more visibility related features. Hence, in order to keep it extensible, the visibility flag. The currently supported values for it will be 'public' which are visible to users and 'private' which are not visible to users.

Impacts

Configuration

None

Database

This involves

  • database migration of adding a column visibility to the datastore_versions table.
  • new table datastore_version_members which columns - id, datastore_version_id, tenant

ReST API

The admin users will be able to list all the datastore versions. The other users will be able to view only public datastore/datastore versions in their list.

This filtering is only for the list calls, not for the GET call. This ensures that the customers can access the datastore if they are provided with the UUID of the datastore version.
