How to Add Database Migration Checks to Your CI/CD Pipeline

Code review catches logic bugs, linting catches style issues, and type checking catches type errors. But what catches dangerous database migrations? Most teams ship migration SQL without any automated safety checks. Here is how to fix that. Why CI Checks for Migrations Database migrations have a unique risk profile compared to application code: Irreversible by default. A deployed app rollback takes seconds. A schema change rollback can take hours or be impossible (data loss from DROP COLUMN). Production-specific risk. A migration that runs in 100ms on dev can take 10 minutes on production with 50M rows. Cascading failures. A single bad lock can queue all queries, exhaust connection pools, and take down the entire application. Low review expertise. Most engineers review SQL migrations less carefully than application code because the risks are not obvious. Automated CI checks solve these problems by catching known-dangerous patterns before the migration is merged. The check runs in secon
