## Group leaders in the optimized topology

With the optimized topology enabled, only the subscriber-only group's group leader receives changes from other nodes in the cluster and it takes on the responsibility of replicating those changes to the other nodes in the subscriber-only group.
With the optimized topology enabled, only the subscriber-only group's group leader receives changes from other data group's write leaders in the cluster and it takes on the responsibility of replicating those changes to the other nodes in the subscriber-only group.

The other voting nodes choose the group leader from a subscriber-only group's nodes.
Once selected, the whole cluster becomes aware of the change and any data group's write leaders then replicate data only to this newly selected group leader node.
