Indexing these columns is a highly recommended practice as replication relies heavily on reading data from the tables that are being replicated.

The execution plans that are generated from those reads should be as optimal as possible.

This happens often, and is not recommended, but it is not unheard of for a column to be directly referenced in an application, such as a linq2sql reference pulled in the schema and relies on that column being returned, or perhaps an INSERT statement was written which inserts a UNIQUEIDENTIFIER into the rowguid.Either adding the column back or leaving the column in place may occur while forcibly removing replication in the back ground. In order to add the rowguid back, a default constraint is required for newsequantialid().This leads to another issue in which the column cannot be dropped unless the default constraint is dropped first.In particular, Merge and Transactional Replication require either a Primary Key or UNIQUEIDENTIFIER column in order to function correctly.In order to manage a change capture -not to be confused with Change Data Capture (CDC) – a unique value is required for every row in a table so replication knows what changes to replicate.
