9.2.1 Core group coordinator
After the membership of the core group stabilizes at runtime, certain members are elected to act as coordinators for the core group. A core group coordinator is responsible for managing the high availability groups within a core group. The following aspects are managed by the core group coordinator:
- Maintaining all group information including the group name, group members and the policy of the group.
- Keeping track of the states of group members as they start, stop, or fail and communicating that to every member.
- Assigning singleton services to group members and handling failover of services based on core group policies.
