A forwarding replica offers a blend of the functionality of the Helix Proxy with the improved performance of a replica.
If you are auditing server activity, each of your forwarding replica
servers must have its own
P4AUDIT log configured.
A forwarding replica can offload read-only commands from an edge server.
To configure the forwarding replica for this use case, set the
ReplicatingFrom:field in the forwarding replica's server spec to the server ID of the edge server. See the Form Fields for p4 server in the Helix Core Command-Line (P4) Reference.
Prior to 2021.2, an edge server between a forwarding replica and a commit server was not supported.
