Sample Ocata Spec for Trove

Introduction paragraph -- what is the motivation for the spec/blueprint? (Don't forget to change the title above to something more relevant.)

Launchpad Blueprint: https://blueprints.launchpad.net/trove/+spec/name-of-blueprint

Problem Description

A detailed description of the problem.

Proposed Change

Here is where you cover the change you propose to make in detail. How do you propose to solve this problem?

If this is one part of a larger effort make it clear where this piece ends. In other words, what's the scope of this effort?

If your specification proposes any changes to the Trove REST API such as changing parameters which can be returned or accepted, or even the semantics of what happens when a client calls into the API, then you should add the APIImpact flag to the commit message. Specifications with the APIImpact flag can be found with the following query:

https://review.openstack.org/#/q/status:open+project:openstack/trove-specs+message:apiimpact,n,z

Code snippets, etc. should be placed in appropriately marked blocks:

# This is a bash command
ls -lf

# sample code
for count in range(1, 10):
    print count

Configuration

Does this impact any configuration files? If so, which ones?

Database

Does this impact any existing tables? If so, which ones? Are the changes forward and backward compatible? Be sure to include the expected migration process

Public API

Does this change any API that an end-user has access to? Are there any exceptions in terms of consistency with other APIs?

Public API Security

If this change proposes a new API, or if this change relates to security on an existing API, provide details here.

What are the expectations of, and implications to security on the Public API.

Python API

Does this change the Python API? If anything was removed, has it been properly marked as deprecated?

CLI (python-troveclient)

Will the Trove CLI need to be modified? If the CLI will just implement the changes mentioned in the Python API section, it may be enough to just mention it here.

Internal API

Does this change any internal messages between API and Task Manager or Task Manager to Guest?

Guest Agent

Does this change behavior on the Guest Agent? If so, is it backwards compatible with API and Task Manager?

Alternatives

This is an optional section, where it does apply we'd just like a demonstration that some thought has been put into why the proposed approach is the best one.

Dashboard Impact (UX)

This section should detail how the dashboard (Horizon) should display the new changes, if relevant. For example, if adding cluster support for Redis, this section could say:

Enabling Redis clustering will simply reuse the existing Launch Cluster
dialog. The Redis datastore will be in the datastore pulldown. When the
user selects Redis the Launch Cluster dialog fields will dynamically
change to display the default Launch Cluster fields.

There will be a new detail overview panel with Redis cluster specific
information.

There are no additional actions to be added at this point for the Redis
cluster.

Implementation

Assignee(s)

Who is leading the writing of the code? Or is this a spec where you're throwing it out there to see who picks it up?

If more than one person is working on the implementation, please designate the primary author and contact.

Primary assignee:

<launchpad-id or None>

Dashboard assignee:

<launchpad-id or None>

Can list additional ids if they intend on doing substantial implementation work on this spec.

Milestones

Target Milestone for completion:

eg. Liberty-1

Work Items

Work items or tasks -- break the feature up into the things that need to be done to implement it. Those parts might end up being done by different people, but we're mostly trying to understand the timeline for implementation.

Upgrade Implications

In this section, describe the upgrade implications (if any) of the proposed change. This could include such details as:

• changes to location of files, or layout of the source tree if this impacts configuration files,
• invalidates old backups,
• changes the CLI in a manner that could impact existing scripting,
• eliminates or adds new notifications (events),
• any changes that an operator or user must perform as part of the upgrade.

If the change has upgrade implications, also remember to:

• add the DocImpact keyword to the commit, and
• provide sufficient information in the commit message or in the documentation bug that gets created.

For more information about the DocImpact keyword, refer to https://wiki.openstack.org/wiki/Documentation/DocImpact

Note: Documentation for the CLI commands are automatically generated from the help strings when a new version of the CLI is released, so a DocImpact keyword is not typically required for python-troveclient changes.

Dependencies

• Include specific references to specs and/or blueprints in Trove, or in other projects, that this one either depends on or is related to.
• Does this feature require any new library dependencies or code otherwise not included in OpenStack? Or does it depend on a specific version of library?

Testing

Please discuss how the change will be tested. We especially want to know what int tests and tempest tests will be added. It is assumed that unit test coverage will be added so that doesn't need to be mentioned explicitly, but discussion of why you think unit tests are sufficient and we don't need to add more tempest tests would need to be included.

Documentation Impact

What is the impact on the docs team of this change? Some changes might require donating resources to the docs team to have the documentation updated. Don't repeat details discussed above, but please reference them here.

References

Please add any useful references here. You are not required to have any references. Moreover, this specification should still make sense when your references are unavailable. Examples of what you could include are¹, ²,³ and⁴.
