Groups Principles of Operation

  • Group Service
    Group services coordinate all the members of a group.
  • Group Members
    Each group has a unique group name, which identifies its members to the group service.
  • Interactions within a Group
    The join call establishes communication between a member and the group service. After the join call returns successfully, the group library continues exchanging heartbeats with the group service. (Heartbeats and other group protocols are not visible to your program code.)
  • Side Effects of Groups
    Group protocol traffic consumes network bandwidth. With fewer than 10 members, using the default activation interval, expect only minimal impact on message latency. More members or a smaller activation interval can increase the impact.
