Sergey Uttsel updated IGNITE-19783:
-----------------------------------
Description:
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
[https://github.com/gridgain/apache-ignite-3/tree/ignite-19783]
