Welcome to a rushed pupdate 19-29. My morning was consumed by other
A reminder: The Placement project holds office hours every Wednesday
at 1500 UTC in the `#openstack-placement` IRC channel. If you have a
topic that needs some synchronous discussion, then is an ideal time.
Just start talking!
# Most Important
The two main things on the Placement radar are implementing Consumer
Types and cleanups, performance analysis, and documentation related
to nested resource providers.
# What's Changed
* The [api-ref](https://docs.openstack.org/api-ref/placement/) has
moved to `docs.openstack.org` from `developer.openstack.org`.
Redirects are in place.
* Both traits and resource classes are [now
cached](https://review.opendev.org/672298) per request, allowing
for some name to id and id to name optimizations.
* A new zuul template is [being
used](https://review.opendev.org/671257) in placement that means
fewer irrelevant tempest tests are run on placement changes.
(Numbers in () are the change since the last pupdate.)

osc-placement is currently behind by 12 microversions.
Add support for multiple member_of. There's been some useful
discussion about how to achieve this, and a consensus has emerged
on how to get the best results.
# Main Themes
## Consumer Types
Adding a type to consumers will allow them to be grouped for various
purposes, including quota accounting.
A WIP, as microversion 1.37, has started.
Cleanup is an overarching theme related to improving documentation,
performance and the maintainability of the code. The changes we are
making this cycle are fairly complex to use and are fairly complex
to write, so it is good that we're going to have plenty of time to
clean and clarify all these things.
# Other Placement
Miscellaneous changes can be found in [the usual
There are two [os-traits
being discussed. And zero [os-resource-classes
# Other Service Users
New discoveries are added to the end. Merged stuff is removed.
Anything that has had no activity in 4 weeks has been removed.
