Topic: #22-Adding Columns to a Large Table with Transactional Replication and Database Mirror
SQL Server 2005 updated replication with the ability to have schema changes replicated to subscriptions. This seemed to be a great solution to custom software releases. You could ALTER a table and the changes would magically appear on the subscriber. Life was great. Also in 2005, database mirroring came along to help with High Availability to a Disaster Recovery site. Life got even better. The problem is with large tables and Tlog heavy changes. This is a step by step process we use to release software to these large tables.
