----------------------------------------------------------------------------
Incorporating [~maximk] and [~davmclau]'s suggestions to put forward a proposal.
Client will send the UUID as part of the metadata field in {{JobUpdateRequest}}
like,
{code}
JobUpdateRequest {
TaskConfig {
JobKey : “role/env/name”
Metadata : {
“Disambiguator” : “FGFJAGGFIAHKHGFAK” #UUID
}
}
}
{code}
Scheduler looks up the active updates for the {{JobKey}} and compare the
{{Disambiguator}} to make sure the request is not a duplicate.
*Pros:*
- Logic is centralized and can benefit all the clients
- No costly diffs are needed
- No explicit API change
*Cons:*
- Scheduler and Client will need changes
- Possibility of identifier collision
- Additional query to the store

> Allow client to store metadata on Update entity
> -----------------------------------------------
>
> Key: AURORA-1711
> URL: https://issues.apache.org/jira/browse/AURORA-1711
> Project: Aurora
> Issue Type: Task
> Components: Scheduler
> Reporter: David McLaughlin
>
> I have a use case where I'm programmatically starting updates via the Aurora
> API and sometimes the request to the scheduler times out or fails, even
> though the update is written to storage and started.
> I'd like to be able to store some unique identifier on the update so that we
> can reconcile this state later. We can make this generic by allowing clients
> to store arbitrary metadata on an update (similar to how they do it with job
> configuration).
