> Cluster ID and tag: properties to identify the cluster
> ------------------------------------------------------

> Key: IGNITE-12111
> URL: https://issues.apache.org/jira/browse/IGNITE-12111
> Project: Ignite
> Issue Type: New Feature
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Priority: Major
> Fix For: 2.9
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> To improve cluster management capabilities two new properties of the cluster
> are introduced:
> # A unique cluster ID (may be either a random UUID or random IgniteUUID).
> Generated upon cluster start and saved to the distributed metastorage.
> Immutable. Persistent clusters must persist the value. In-memory clusters
> should keep the generated ID in memory and regenerate it upon restart.
> # Human-readable cluster tag. Generated by default to some random (but still
> meaningful) string, may be changed by user. Again survives restart in
> persistent clusters and is regenerated in in-memory clusters on every restart.
> These properties are exposed to standard APIs:
> # EVT_CLUSTER_TAG_CHANGED event generated when tag is changed by user;
> # JMX bean and control utility APIs to view ID and tag and change tag.
