The rs_address special datatype makes a unique subscription resolution technique possible: bitmaps of the rs_address datatype (based on the underlying int datatype) are compared with a bitmask in a subscription’s where clause to determine whether a row should be replicated.
To use this subscription resolution method:
Create tables that use columns of the int datatype.
Create a replication definition that includes these columns in the column list, but declare the datatype as rs_address instead of int.
You must include any columns that use the rs_address datatype in the searchable columns clause of the replication definition in order to perform bitmap comparison using the where clause.
See “Bitmap subscriptions” for more information on using rs_address columns for bitmap subscription resolution.
