Writes a Flyway database migration for this project following the team's rules for naming, editing and renaming, so migrations from different developers don't collide and deployed databases stay valid. Use whenever a change needs a new table, column, index or data fix, or the user mentions a schema change or migration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Write a database migration Migrations live in `src/main/resources/db/migration`. 1. Follow the naming the folder already uses. In a folder with no migrations yet, use `V<yyyyMMddHHmm>__<what_it_does>.sql` in UTC: unlike `V7`, `V8`, timestamps don't collide when two developers add a migration on different branches. With numbered names, take the next number after the highest one on the main branch, and renumber yours if someone merges first. 2. Never edit a migration that is on the main branch. It may already have run on a shared database, and Flyway fails validation when the checksum changes. Write a new migration instead. 3. Make destructive changes in two releases. To rename or drop a column, first add the new column and write to both, and drop the old one in a later migration once no running version reads it. 4. Keep each migration to one purpose. Put data fixes in their own file, and make them safe to run on a database where the fix is already done. 5. Don't let Hibernate create the schema: `spring.jpa.hibernate.ddl-auto` stays `validate` or `none`. …

How to install
mdr add a-pavithraa/springboot-skills-marketplace/db-migration@sha256:fb0a3b5e380dc284The line at the top of this page pins the label git:20261023.b8e5633, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
