Properties

BigqueryDestination

The destination BigQuery structure that contains both the dataset location and corresponding schema config. The output is organized in one table per resource type. The server reuses the existing tables (if any) that are named after the resource types, e.g. "Patient", "Observation". When there is no existing table for a given resource type, the server attempts to create one. When a table schema doesn't align with the schema config, either because of existing incompatible schema or out of band incompatible modification, the server does not stream in new data. One resolution in this case is to delete the incompatible table and let the server recreate one, though the newly created table only contains data after the table recreation. BigQuery imposes a 1 MB limit on streaming insert row size, therefore any resource mutation that generates more than 1 MB of BigQuery data will not be streamed. Results are written to BigQuery tables according to the parameters in BigQueryDestination.WriteDisposition. Different versions of the same resource are distinguishable by the meta.versionId and meta.lastUpdated columns. The operation (CREATE/UPDATE/DELETE) that results in the new version is recorded in the meta.tag. The tables contain all historical resource versions since streaming was enabled. For query convenience, the server also creates one view per table of the same name containing only the current resource version. The streamed data in the BigQuery dataset is not guaranteed to be completely unique. The combination of the id and meta.versionId columns should ideally identify a single unique row. But in rare cases, duplicates may exist. At query time, users may use the SQL select statement to keep only one of the duplicate rows given an id and meta.versionId pair. Alternatively, the server created view mentioned above also filters out duplicates. If a resource mutation cannot be streamed to BigQuery, errors will be logged to Cloud Logging (see Viewing error logs in Cloud Logging).

DeidentifiedStoreDestination

The destination FHIR store for de-identified resources. After this field is added, all subsequent creates/updates/patches to the source store will be de-identified using the provided configuration and applied to the destination store. Resources deleted from the source store will be deleted from the destination store. Importing resources to the source store will not trigger the streaming. If the source store already contains resources when this option is enabled, those resources will not be copied to the destination store unless they are subsequently updated. This may result in invalid references in the destination store. Before adding this config, you must grant the healthcare.fhirResources.update permission on the destination store to your project's Cloud Healthcare Service Agent service account. The destination store must set enable_update_create to true. The destination store must have disable_referential_integrity set to true. If a resource cannot be de-identified, errors will be logged to Cloud Logging (see Viewing error logs in Cloud Logging).

ETag

The ETag of the item.

public virtual string ETag { get; set; }
Property Value
Type Description
string

ResourceTypes

Supply a FHIR resource type (such as "Patient" or "Observation"). See https://www.hl7.org/fhir/valueset-resource-types.html for a list of all FHIR resource types. The server treats an empty list as an intent to stream all the supported resource types in this FHIR store.
