Detailed Description

Defines a cluster group which contains all or a subset of cluster nodes.

Cluster group allows to group cluster nodes into various subgroups to perform distributed operations on them. The IgniteCluster interface itself also contains the ClusterGroup which makes an instance of IgniteCluster into a cluster group containing all cluster nodes. Use IgniteCluster::AsClusterGroup() to get the cluster group in this case.
