Here is the status update / focus setting mail about notification work
for week 27.

[Undecided] https://bugs.launchpad.net/nova/+bug/1684860 Versioned 
server notifications don't include updated_at
Takashi proposed the fix https://review.openstack.org/#/c/475276/ that 
is ready for the cores to look at.

[Low] https://bugs.launchpad.net/nova/+bug/1696152 nova notifications
use nova-api as binary name instead of nova-osapi_compute
Agreed not to change the binary name in the notifications. Instead we
make an enum for that name to show that the name is intentional.
Patch has been proposed:  https://review.openstack.org/#/c/476538/

[Undecided] https://bugs.launchpad.net/nova/+bug/1699115 api.fault 
notification is never emitted
It seems that the legacy api.fault notification is never emited from 
nova. More details and the question about the way forward is in a 
separate ML thread 

[Undecided] https://bugs.launchpad.net/nova/+bug/1698779 aggregate 
related notification samples are missing from the notification dev-ref
It is a doc generation bug. Fix and improvement on doc generation has 
been proposed https://review.openstack.org/#/c/475349/ and reviewed by 
the subteam. So it is ready for the cores to look at.

[Undecide] https://bugs.launchpad.net/nova/+bug/1700496 Notifications 
are emitted per-cell instead of globally
Fix is to configure a global MQ endpoint for the notifications in cells 
v2. Patch is beinf worked on: https://review.openstack.org/#/c/477556/

Versioned notification transformation
Couple of patches has been merged but we still have a bunch ready from 
the subteam perspective:

Searchlight integration
bp additional-notification-fields-for-searchlight
Two patches merged last week. The BDM addition just needs a second +2 

Besides the BDM patch we are still missing the Add tags to 
instance.create Notification https://review.openstack.org/#/c/459493/ 
patch but that depends on supporting tags and instance boot 
https://review.openstack.org/#/c/394321/ which is still not ready.

Small improvements
* https://review.openstack.org/#/c/428199/ Improve assertJsonEqual
error reporting
* https://review.openstack.org/#/q/topic:refactor-notification-samples
Factor out duplicated notification sample data
This is a start of a longer patch series to deduplicate notification
sample data. The third patch already shows how much sample data can be
deleted from nova tree. We added a minimal hand rolled json ref
implementation to notification sample test as the existing python json
ref implementations are not well maintained.

Weekly meeting
The notification subteam holds it's weekly meeting on Tuesday 17:00 UTC
on openstack-meeting-4. The next meeting will be held on 04th of July.
