$import & /fhir/$import

$import is an implementation of the upcoming FHIR Bulk Import API. This is an asynchronous Operation, which returns url to monitor progress. There are two versions of this operation - /fhir/$import accepts data in FHIR format, /$import works with Aidbox format.

Resource requirements for all import operations:

Operation
id
resourceType
/$import
Required
Not required
/fhir/$import
Required
Not required
Keep in mind that $import does not validate inserted resources for the sake of performance. Pay attention to the structure of data you insert and use the correct URL for your data format, i.e.: use /fhir prefix for FHIR data.
Please consider using Asynchronous validation API to validate data after $import

Note

For performance reasons $import does raw upsert into resource table without history update. If you want to store the previous version of resources in history, please set update = true
With this flag Aidbox will update history for updated resources. For each resource:
  • if resource was not present in DB before the import, the import time will be the same.
  • if resource was present in DB before and it's updated during the import, it will double the time importing this resource because of additional insert operation into _history table.

/v2/$import on top of the Workflow Engine

Improved version of the $import operation, to enhance its reliability and performance. By implementing this operation on top of the Workflow Engine, it allows the $import operation to be more reliable, continue work after restarts, and handle errors correctly. The Task API also enables the operation to accept multiple requests and execute them from a queue while simultaneously processing multiple items from the "inputs" field (with a default of two items processed simultaneously). Users can monitor the status of the operation through the Monitoring.
In the future, the ability to list and cancel $import operations will be added, as well as detailed progress info on the operation.
Changes in the new $import API:
  1. 1.
    Executing more than one import with the same id is not possible. Users can omit the `id` field from the request, allowing Aidbox to generate the ID.
  2. 2.
    The status of the workflow can be accessed with a GET request to /v2/$import/<id> instead of /BulkImportStatus/<id>. The URL for the import status is returned in the content-location header of the $import request.
This feature is not available in Multibox​
To start import make a POST request to /v2[/fhir]/$import:
Request
Response
POST /v2/fhir/$import
Accept: text/yaml
