Situation
During an internship, I was assigned to run a database migration that would consolidate two legacy tables into one. I tested it thoroughly in staging but underestimated the difference in dataset size between staging and production.
Task
I executed the migration during a scheduled maintenance window. My job was to ensure zero data loss and a rollback plan if anything went wrong.
Action
The migration ran fine in staging but timed out in production after 40 minutes, locking the table and bringing down the payment confirmation feature for 22 minutes. I immediately rolled back using the backup snapshot, communicated the impact clearly to my manager in Slack within five minutes of the outage, and prepared a post-mortem the next day outlining three root causes: no production-scale dry run, no row-count comparison check, and no circuit breaker on the migration query.
Result
The 22-minute outage affected 340 transactions, all of which were successfully retried. I implemented the post-mortem recommendations before re-running the migration the following week — this time in batches of 10,000 rows, which completed in 8 minutes with zero downtime. My manager said the post-mortem was one of the best she had seen from an intern.
