<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">I'm not sure I understand the first question, but it seems like you are asking how the default capabilities are determined. First, they should all be documented. Secondly, we can
have defaults setup by migrations. I agree that this is not as seamless as a default config file, and that segways into question two.<br>
<br>
We want to eventually serve this data to the customers. As far as I know, there is no precedent in Openstack to serve configuration file data to customers. All customer presented data should be contained in the database, not in flat files. Additionally, management
via the api becomes much more complex when I have to write to files instead of adding removing database rows.<br>
<br>
As far as enabled/disabled capabilities, having enabled/disabled for each feature is more prone to errors or inconsistencies. Having a list of allowed features solves the same problem without needing to maintain a full set of features and associated flags for
each datastore/version. We agreed this approach much cleaner and simpler than the prior.<br>
<br>
Implementation will be coming shortly - I'm still working on that. I'll let you know as soon as I have something ready for review.<br>
<br>
Also, supposedly, the discussions we had last week are recorded and available via some means, but I don't know where. A lot of this was discussed there if you weren't able to make it.

<b>Design: What is a capability?</b><br>
A capabilities is an attribute of a datastore/version that allows dynamic code flow for different datastore/versions, The presence of a capability determines which code path is taken. A capability is an ID, a friendly name (used in our code), and a lengthy
description (for displaying to the user). <br>
<br>
<b>Design: Where do they live?</b><br>
Capabilities will live in their own table. In addition, there will be an association table to map between datastore versions and capabilities.<br>
<br>
<b>Design: Why isn't this in config files?<br>
</b>First, they will be able to be viewed by customers, and modified by operations. That does not lend itself to config files. Additionally, we should be able to change a datastores capabilities without a restart.<br>
<br>
<b>Operations: What happens if the capabilities table is not populated?</b><br>
We are setting everything to be <b>default off</b> for all features. For mysql to support ephemeral_volumes it would need to be added to the capabilities table and properly associated to each version of mysql.
<br>
<br>
<b>Operations: How do you manage them?</b><br>
For the first pass, trove-manage commands. There will be a add_capability, remove_capability, associate_capability_with_datastore, and unassociate_capability_from_datastore (name are completely off the top of my head and subject to discussion/change).<br>
<br>
<b>Development: When/where are capabilities checked/determined?</b><br>
Any time you would want to fork paths. The check for ephemeral_volume would happen right before the cinder volume is created, whereas the database capability would be checked as soon as possible in the api layer.
<br>
<br>
<b>Development: How are capabilities checked?</b><br>
This is still to be determined.<br>
<br>
Option one (the one discussed at the meetup): <br>
if(cfg.cababilites.mysql.ephemeral_volumes):<br>
do_code()<br>
<br>
Option two:<br>
if "ephemeral_volumes" in datastore.manager.capabilities)<br>
do_code()<br>
<br>
The advantages of option one is consistency in checking the cfg object for configuration like things. I think that is worse than checking a property of the datastore. The advantage of the second way is that is more cleanly expresses what is happening under
the hood without any additional cost. I have the second option about complete, so we can see what that looks like soon.<br>
<br>
Most of this was discussed and agreed upon last week, I just wanted to recap and confirm with everyone on what our objectives and goals are. If there are unanswered questions, lets discuss sooner rather than later.<br>
<b><br>
<br>
</b>- KPom<br>
<b><br>
<br>
Bonus: API discussion for future development (not right now)<br>
</b>I suggest we expose only the capabilities that belong to a specific datastore. As a customer, I shouldn't know every feature available, just the ones on the datastore they are looking at.<br>
<br>
GET /{tenant_id}/datastores/{datastore_version_id}/capabilities<br>
<br>
<br>
Eventually, we would want the following admin routes available, but that is mitigated by the trove-manage stuff.<br>
<br>
[GET | PUT | POST | DELETE] /capabilities<br>
[POST | DELETE] /datastores/datastore_version_id/capabilities<br>
