DB

This module primarily contains SQL files for the URLs database. The most central tables are EC_DOMAIN, EC_URL and EC_PAGE_DATA.

Flyway

The system uses flyway to track database changes and allow easy migrations, this is accessible via gradle tasks.

• flywayMigrate
• flywayBaseline
• flywayRepair
• flywayClean (dangerous as in wipes your entire database)

Refer to the Flyway documentation for guidance. It's well documented and these are probably the only four tasks you'll ever need.

If you are not running the system via docker, you need to provide alternative connection details than the defaults (TODO: how?).

The migration files are in resources/db/migration. The file name convention incorporates the project's cal-ver versioning; and are applied in lexicographical order.
