The Group service consists of a client library and and active-standby server process running on the system controller nodes.
A group is identified by a well-known ClusterUniqueId, or a dynamically created one. A group can be named via the Name service and all APIs that require a group will also accept a string name.
Synergy
A group can be named via the Name service. The Group service interacts with the messaging service, allowing several modes:
- broadcast messages to all members of the group
- send to master
- local round robin
The default mode is defined by the group.
