Subject Cluster ID and tag: identification of the cluster
Date Wed, 28 Aug 2019 08:00:20 GMT
Hello folks,

I would like to propose implementing new properties to identify the cluster
and simplify managing it by external tools (e.g. custom scripts built on
top of standard Control Utility).

These properties are Cluster ID (UUID) and Cluster tag (String) exposed
through existing IgniteCluster public API.

Both properties are generated upon cluster startup (before activation if
the cluster requires it) and survived restarts if cluster is configured in
persistent mode and regenerated again if it is an in-memory cluster.

Cluster ID is immutable and useful more for automated tools while Cluster
tag is mutable (may be changed by user) and is supposed to be human
readable to view it in any GUI or web-based management solutions.

I already created a ticket [1] with some more technical details and invite
community to discuss this feature.
