It break the current behavior. I think it should be documented, perhaps in
release notes?

Unfortunately we don't have release notes right now as we've yet to complete
our first release. We have started exercising a more formalized deprecation
process (evidence of tracking here: AURORA-423). However, it would have been
good form for us to notify on the mailing list. In this particular case, we
realized after the fact that a change in client updater behavior (removing
client-side health checks during updates: AURORA-361) created a case where
updates could be extremely risky if these two parameters were misaligned. We
decided it was better to prevent an update like this to mitigate risk.

> Project: Aurora
> Issue Type: Bug
> Components: Client
> Affects Versions: 0.6.0
> Reporter: Bhuvan Arumugam
>
> The create fail, if {{HealthCheckConfig.initial_interval_secs}} is specified
> and {{UpdateConfig.watch_secs}} is not specified.
> If {{UpdateConfig.watch_secs}} is not specified, it should default to
> sensible default. It should report following error only if the user have
> defined {{UpdateConfig.watch_secs}} and it is lesser than expected seconds.

> AppName.aurora
> FATAL]
> You have specified an insufficiently short watch period (45 seconds) in your
> update configuration.
> Your update will always succeed. In order for the updater to detect health
> check failures,
> UpdateConfig.watch_secs must be greater than 330 seconds to account for an
> initial
> health check interval (180 seconds) plus 5 consecutive failures at a check
> interval of 30 seconds.
