File Replace #3220
Description
To support Provenance, we need to add versioning/replace functionality for DataFile objects.
Basics:
- User may replace an existing dataset file with a new one:
- via UI
- via API
- File versions are tied to dataset versions
Technical notes:
Internal storage:
- DataFile will have two extra fields:
- Root DataFile id
- Previous DataFile id
| DataFile id | Root DataFile ID | Previous DataFile ID |
|---|---|---|
| 1 | 1 | null |
| 5 | 1 | 1 |
| 7 | 1 | 5 |
| 35 | 1 | 7 |
