Hi gibi,

Thank for the info. Searchlight team is working on a patch to support the
versioned Nova. Hopefully, it will be released in Stein-1.

Re: [openstack-dev] [nova][searchlight][designate][telemetry][mistral][blazar][watcher][masakari]Possibledeprecation of Nova's legacy notification interface

2018-09-17 Thread Balázs Gibizer 

Hi,

On the Stein PTG the nova team agreed to deprecate the legacy, 
unversioned notification interface of nova. We also agreed that we will 
not try to remove the legacy notification sending from the code any 
time soon. So this deprecation means the following:
* by default configuration nova will only emit versioned notifications, 
but the unversioned notifications still can be turned on in the 
configuration.
* nova will not maintain the legacy notification code path further, so 
it can break


I pushed the deprecation patch [2] but it will only be merged after the 
remaining versioned notification transformation patches [3] are merged.


Cheers,
gibi

Dear Nova notification consumers!


The Nova team made progress with the new versioned notification 
interface [1] and it is almost reached feature parity [2] with the 
legacy, unversioned one. So Nova team will discuss on the upcoming 
PTG the deprecation of the legacy interface. There is a list of 
projects (we know of) consuming the legacy interface and we would 
like to know if any of these projects plan to switch over to the 
new interface in the foreseeable future so we can make a well 
informed decision about the deprecation.



* Searchlight [3] - it is in maintenance mode so I guess the answer 
is no

* Designate [4]
* Telemetry [5]
* Mistral [6]
* Blazar [7]
* Watcher [8] - it seems Watcher uses both legacy and versioned nova 
notifications
* Masakari - I'm not sure Masakari depends on nova notifications or 
not
