> Key: IGNITE-5552
> URL: https://issues.apache.org/jira/browse/IGNITE-5552
> Project: Ignite
> Issue Type: Improvement
> Components: managed services
> Affects Versions: 1.7
> Reporter: Alexey Goncharuk
> Assignee: Alexey Goncharuk
> Fix For: 2.2
>
>
> This behavior was observed in a real cluster of hundreds of nodes and
> hundreds of services.
> After a ~30 new nodes startup, we expected node singletons to be deployed
> immediately, but the services were deployed with ~4hr delay on last nodes.
> The reason for this is the fact that ALL service deployments are recalculated
> on ALL discovery events. In this case, a single discovery event was processed
> in a time span of 2-5 minutes, which with the lateAffinityAssignment=true
> yielded a 4hr delay for the last node.
> The quick change that may improve things a lot is aborting current assignment
> calculations if there is a pending discovery event needs to be processed.
> The rest of the optimizations are put to
