The change adds a new column to the MESSAGE_QUEUE table called AUDIT_RELATED_ID. This field is populated transparently, using a dictionary mapping Thread IDs to Message IDs, populated by the inbox handlers. The existing RELATED_ID field has too many semantics associated with them, among other things the FSM code uses them this field in tracking state changes. The change set also improves the consistency of inbox names. The IndexClient was buggy and populated its outbox with a UUID. This is fixed. All Service2Service outboxes are now prefixed with 'pp:' to make them even easier to differentiate. |

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.
flywayMigrateflywayBaselineflywayRepairflywayClean(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.
