admin:forest-add-replica(
   $config as element(configuration),
   $master-id as xs:unsignedLong,
   $replica-id as xs:unsignedLong
) as element(configuration)

Summary

Parameters
config A configuration specification, typically as returned from one of the Admin module functions.
master-id The ID of the master forest to which to add the replica forest (for example, xdmp:forest("MasterForest") ).
replica-id The ID of the replica forest to add to the master forest (for example, xdmp:forest("ReplicaForest") ).

  let $forest := xdmp:forest("Documents")
