Field notes
The workflow shown begins by replaying 37 base migrations and seeding synthetic rows; one sample mentions 1,000,000 rows in an orders table. The page names PostgreSQL 14–17 and shows golang-migrate, Flyway, dbmate, and Prisma alongside the workflow. It describes the runner as isolated from networks and secrets, then discarded after a run. These are homepage descriptions and examples, not independently verified performance results.
