Database Migration on Startup

https://docs.spring.io/spring-boot/docs/current/reference/html/howto-database-initialization.html#howto-execute-flyway-database-migrations-on-startup

Flyway database migration is automatically triggered on startup if "org.flywaydb:flyway-core" dependency is present in the application's classpath.

The migration script naming convention is V<version>_<name>.sql where:

• <version> is an underscore separated version, such as "1" or "1_2".

The migration script default location is "classpath:db/migration[/{vendor}]", but it can be overridden with the "spring.flyway.locations" property, which should contain a comma-separated list of one or more classpath: or filesystem: locations.

spring.flyway.locations=classpath:db/migration,filesystem:/opt/migration

The {vendor} placeholder is set according to the type of database.
