> h3. *Motivation*
> In https://issues.apache.org/jira/browse/IGNITE-19736 we set corePoolSize=1
> for DistributionZoneManager#executor to ensure that all data nodes
> calculation tasks per a zone are executed in order of creation. But we need
> more threads to process this tasks. So we need to create
> StripedScheduledExecutorService and all tasks for the same zone must be
> executed in one stripe. The pool to execute the task is defined by a zone id.
> h3. *Definition of Done*
> # StripedScheduledExecutorService is created and used instead of single
> thread executor in DistributionZoneManager.
> # All tasks for the same zone must be executed in one stripe.
> h3. *Implementation Notes*
> I've created a draft StripedScheduledExecutorService in a branch
