This PR initiates the rework of Zitadel's backend to state-persisted objects. This change is a step towards a more scalable and maintainable architecture. ## Changes * **New `/backend/v3` package**: A new package structure has been introduced to house the reworked backend logic. This includes: * `domain`: Contains the core business logic, commands, and repository interfaces. * `storage`: Implements the repository interfaces for database interactions with new transactional tables. * `telemetry`: Provides logging and tracing capabilities. * **Transactional Tables**: New database tables have been defined for `instances`, `instance_domains`, `organizations`, and `org_domains`. * **Projections**: New projections have been created to populate the new relational tables from the existing event store, ensuring data consistency during the migration. * **Repositories**: New repositories provide an abstraction layer for accessing and manipulating the data in the new tables. * **Setup**: A new setup step for `TransactionalTables` has been added to manage the database migrations for the new tables. This PR lays the foundation for future work to fully transition to state-persisted objects for these components, which will improve performance and simplify data access patterns. This PR initiates the rework of ZITADEL's backend to state-persisted objects. This is a foundational step towards a new architecture that will improve performance and maintainability. The following objects are migrated from event-sourced aggregates to state-persisted objects: * Instances * incl. Domains * Orgs * incl. Domains The structure of the new backend implementation follows the software architecture defined in this [wiki page](https://github.com/zitadel/zitadel/wiki/Software-Architecturel). This PR includes: * The initial implementation of the new transactional repositories for the objects listed above. * Projections to populate the new relational tables from the existing event store. * Adjustments to the build and test process to accommodate the new backend structure. This is a work in progress and further changes will be made to complete the migration. --------- Co-authored-by: Copilot <[email protected]> Co-authored-by: Iraq Jaber <[email protected]> Co-authored-by: Iraq <[email protected]> Co-authored-by: Tim Möhlmann <[email protected]>
