SQL Server CDC: Remember It's Not Free

Someone recently recommended that a developer use SQL Server's CDC (Change Data Capture) to create a history record for a transactional table because doing that work in a stored procedure "makes this stored procedure slow". Remember that there is no magic in CDC; it's not free.

Based on the research I did for this article:

Performance Testing SQL Server 2008's Change Data Capture functionality

"The average penalty for CDC with full recovery is 10.51%."
