Night school: migrations and schema discipline
Six late evenings on safe migrations, zero-downtime patterns, and rollback drills.
6 nights Cohort 720,000 KRW
Schema changes scare teams because tutorials skip locking behavior. We rehearse expand-contract flows and measure impact before touching prod-like datasets.
Included focus areas
- Expand-contract with reversible steps
- Index creation without surprise locks
- Data backfills with chunking
- Shadow reads before flipping writes
- Observing slow queries with explain plans
Outcomes
- Draft a migration plan with explicit rollback
- Run a staged deploy on a copy dataset
- Communicate risk to non-engineers clearly
