Deployers with existing legacy data sets will need to consider how to prepopulate those records into Registry. There are several possible approaches, each with different considerations:
- For large datasets (> ~50k), BulkLoad offers the best performance.
- For small datasets (< ~100), Manual Enrollment offers the lowest setup overhead.
- In the middle, API Enrollment or OIS Import are probably the best options.
- All options except OIS Import require data to be available locally for import.
- OIS Import can connect to upstream datasets and synchronize them without requiring local copies.
Linkage With Upstream Data Sources
Organizational Identity Sources allow for records to be synced from upstream sources. After the initial load, internal database keys must be in place for subsequent updates to happen automatically.
- OIS Import will set the internal keys automatically.
- BulkLoad will set the internal keys automatically when the inbound file is configured appropriately. See the documentation for details.
- Manual Enrollment will set the internal keys if Enrollment Sources are used.
- Setting the keys via the API is not currently supported.
