When you select the Full database replica mode, the RPS node keeps a full copy of the database synchronized with the production database.
The benefits of the Full database replication database mode are:
Can be used to perform extract operations without impacting the operation of the production database.
The replicated database can be used as an emergency database backup and for disaster recovery.
Can acquire a primary database role in a negotiated or hostile takeover; that is, you can use a single SDS database for data recovery and RPS purposes.
Column-mapping methods and virtual properties can access any persistent data.
This mode does not require the RPS data store to be recreated following changes to the RPS mapping.
