Write FHIR data to NDJSON files

Writes the data from a data source to a directory of NDJSON files. Each resource type is written to one or more files named with the resource type, a partition number and an identifier of the write, for example "Patient.00000-<write id>.ndjson".

ds_write_ndjson(ds, path, save_mode = SaveMode$ERROR, file_name_mapper = NULL)

Arguments

save_mode

file_name_mapper

An optional function that can be used to customise the mapping of the resource type to the file name. Currently not implemented.

Value

A list with element file_infos, containing a list of files created. Each file has fhir_resource_type and absolute_url.
