# Data Model: Migration Process and UI Redesign
|
|
|
|
## Entities
|
|
|
|
### Environment
|
|
Represents a Superset instance.
|
|
|
|
| Field | Type | Description |
|
|
|-------|------|-------------|
|
|
| `id` | UUID | Primary Key |
|
|
| `name` | String | Display name (e.g., "Development", "Production") |
|
|
| `url` | String | Base URL of the Superset instance |
|
|
| `credentials_id` | String | Reference to encrypted credentials in the config manager |
|
|
|
|
### DatabaseMapping
|
|
Represents a mapping between a database in the source environment and a database in the target environment.
|
|
|
|
| Field | Type | Description |
|
|
|-------|------|-------------|
|
|
| `id` | UUID | Primary Key |
|
|
| `source_env_id` | UUID | Foreign Key to Environment (Source) |
|
|
| `target_env_id` | UUID | Foreign Key to Environment (Target) |
|
|
| `source_db_uuid` | String | UUID of the database in the source environment |
|
|
| `target_db_uuid` | String | UUID of the database in the target environment |
|
|
| `source_db_name` | String | Name of the database in the source environment (for UI) |
|
|
| `target_db_name` | String | Name of the database in the target environment (for UI) |
|
|
| `engine` | String | Database engine type (e.g., "clickhouse", "postgres") |
|
|
|
|
### MigrationJob
|
|
Represents a single migration execution.
|
|
|
|
| Field | Type | Description |
|
|
|-------|------|-------------|
|
|
| `id` | UUID | Primary Key |
|
|
| `source_env_id` | UUID | Foreign Key to Environment |
|
|
| `target_env_id` | UUID | Foreign Key to Environment |
|
|
| `status` | Enum | `PENDING`, `RUNNING`, `COMPLETED`, `FAILED`, `AWAITING_MAPPING` |
|
|
| `replace_db` | Boolean | Whether to apply database mappings |
|
|
| `created_at` | DateTime | Timestamp of creation |
|
|
|
|
## Relationships
|
|
- `DatabaseMapping` belongs to a pair of `Environments`.
|
|
- `MigrationJob` references two `Environments`.
|
|
|
|
## Validation Rules
|
|
- `source_env_id` and `target_env_id` must be different.
|
|
- `source_db_uuid` and `target_db_uuid` must belong to databases with compatible engines (optional warning).
|
|
- Mappings must be unique for a given `(source_env_id, target_env_id, source_db_uuid)` triplet.
