A replication definition describes the primary table to Replication Server, specifying the columns you want to copy.
It may also describe attributes of the replicate table. Replicate tables that match the specified characteristics can subscribe to the replication definition. You can create multiple replication definitions for the same primary table, each customized for a particular use.
To create a replication definition, you can execute one of the following:
Information about each replication definition is sent to each qualifying Replication Server with a route from the primary Replication Server. There are restrictions in mixed-version systems.
Replication definitions are stored in the rs_objects and rs_columns system tables in the RSSD. The primary version of a replication definition resides at the primary Replication Server.
