---------------------------------------------------
> Improve Decanter scheduler to reduce latency
> --------------------------------------------
>
> Key: KARAF-4610
> URL: https://issues.apache.org/jira/browse/KARAF-4610
> Project: Karaf
> Issue Type: Improvement
> Components: decanter
> Reporter: Jean-Baptiste Onofré
> Assignee: Jean-Baptiste Onofré
> Fix For: decanter-1.1.1
>
>
> The Decanter simple scheduler is actually a bit too simple ;)
> All Runnable Collectors are executed sequentially within the same thread in
> the simple scheduler.
> This way we may have big delays in the results. The scheduler is configured
> to run every 60 seconds. But for some JMX metricts the execution interval is
> rather 78 seconds or even more.
> 1) Instead of sleeping a fix time the scheduler should restart at a fix
> interval (even if the collectors need a longer time to execute).
> 2) Runnable Collectors should be executed in parallel.
> For 1, we could use:
> {{java.util.concurrent.Executors.newSingleThreadScheduledExecutor();}}
> For 2, we could use: {{java.util.concurrent.Executors.newCachedThreadPool();}}
