Subscriber-only nodes and groups

Subscriber-only nodes and groups offer a powerful way to build read scaling into your PGD cluster.

• The Overview of durability options introduces how subscriber-only nodes and groups work in PGD.

• Creating Subscriber-only groups and nodes explains how to create a subscriber-only group and node.

• Joining nodes to a Subscriber-only group explains how to join a node to an existing subscriber-only group which has members.

• Optimizing subscriber-only groups provides details on how to configure the PGD subscriber-only optimized topology feature which uses a group leader for more efficient replication.
