如何使用 SAP Cloud SDK 执行深度更新

Question

We are currently trying for performance reasons to execute a deep update on an entity structure exposed as OData service using the SAP Cloud SDK. From our understanding using the replacingEntity() strategy on the update request, we want to send the complete structure down to the OData service similar to what is described for the deep insert use case here:

https://blogs.sap.com/2017/12/07/step-20-with-s4hana-cloud-sdk-create-and-deep-insert-with-the-virtual-data-model-for-odata/

However, when doing so we noticed that only the entity fields are sent and none of the navigational properties. Having debugged/browsed through the SDK this seems to be the intended behaviour as can be seen in the following method:

com.sap.cloud.sdk.s4hana.datamodel.odata.helper.FluentHelperUpdate.getQueryBuilder() {
    [...]
    final Map<String, Object> fieldsForUpdate = getFieldsForUpdate(); // does not include navigations
    [...]
}

Is there some configuration option when making the request for making a deep update? Or is one supposed to retreat to batch requests to the backend instead? In case this is not a supported a remark whether this is on the roadmap would also be greatly appreciated!

At the time of this writing, the SAP Cloud SDK for Java does not provide the functionality "deep update". I will update this answer if this feature will be covered.
