FHIR OperationDefinition

Pathling provides a FHIR® REST interface, and the $import operation is an extended operation defined on that interface.

This operation allows FHIR R4 data to be imported into the server, making it available for query via other operations such as search and aggregate. This operation accepts the NDJSON format, and links to retrieve that data are provided rather that sending the data inline within the request itself. This is to allow for large data sets to be imported efficiently.

Currently Pathling supports retrieval of NDJSON files from Amazon S3 (s3://), HDFS (hdfs://) and filesystem (file://) URLs. Authentication is supported for S3, see Configuration and deployment for details.
