# 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](https://documentation.red-gate.com/fd/flyway-documentation-138346877.html) 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](src/main/resources/db/migration). The file name convention
|
|
incorporates the project's cal-ver versioning; and are applied in lexicographical order.
