Pitfalls with SQL rollbacks and automated database deployments

The article by Bob Walker explores the challenges and inefficiencies of performing SQL rollbacks in database deployments, suggesting that rolling forward is typically a more effective strategy. Rollbacks can be complex and risky, often leading to data loss or corruption, and are rarely justified except in specific, limited scenarios. The article emphasizes that the effort required to roll back a database change often surpasses that of rolling forward with a fix, especially once users have begun interacting with the updated system. Walker argues for prioritizing fast and safe deployments and making database changes backward compatible to reduce deployment risk. He also highlights the pitfalls of relying on backups and rollback scripts, noting that they often have a limited lifespan and can complicate the deployment process. Ultimately, the article advocates for focusing on improving deployment processes rather than on elaborate rollback strategies, as rolling forward can be more efficient and less disruptive.
