Bertrand Delacretaz commented on SLING-3278:
--------------------------------------------
Is the 500ms "caching time" used to expire results from the cache, and is it
the same for all results?
If yes I think results will need different times to live depending on their
nature - I'd suggest adding a method to the HealthCheckExecution result that is
used to expire results from the cache, maybe getTimeToLiveMsec(). For now this
can be based on this default value, but it will allow results to provide
appropriate values later on, without changing the API.
> Provide a HealthCheckExecutor service

> Goals:
> * Be able to get an overall (aggregated) result as quickly as possible
> (ideally <2sec)
> * Whenever possible, return most current results (e.g. for a memory check)
> * Provide a declarative way for async checks (async checks should be the
> exception though)
> Approach
> * Run checks in parallel
> * Make sure long running (or even stuck) checks are timed out
> * If a health check must run asynchronously (because its execution time
> cannot be optimized), it should be enough to just specify a service property
> (e.g. "hc.async").
