----------------------------------------
Summary: 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
Fix For: 2.8
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.
