--------------------------------------------
Assignee: Mirza Aliev
> Implement restoring of global states of DistributionZoneManager after restart
> -----------------------------------------------------------------------------
>
> Key: IGNITE-19574
> URL: https://issues.apache.org/jira/browse/IGNITE-19574
> Project: Ignite
> Issue Type: Bug
> Reporter: Mirza Aliev
> Assignee: Mirza Aliev
> Priority: Major
> Labels: ignite-3
>
> In https://issues.apache.org/jira/browse/IGNITE-19061 we have provided design
> for a correct restart of a node and recovering all Distributed Zones states.
> In this ticket we want to restore
> {{DistributionZoneManager#nodesAttributes}}, check that
> {{DistributionZoneManager#logicalTopology}} is restored correctly. To achieve
> restoring {{DistributionZoneManager#nodesAttributes}}, we need to save it
> synchronously to Vault when we handle
> {{DistributionZoneManager#createMetastorageTopologyListener}}, and read this
> value on a restart in {{DistributionZoneManager#start}}
> Details could be found in the design document.
> As a result, this global states must be restored to the state that they had
> before restart. Test for restart scenarios must be provided, so we want to
> test, that any restart of a node leads to correct global states restoring,
> meaning that their state before restart are restored.
