Is there a way to send OData batch requests using either ODataQueryBuilder or VDM generated classes?
Example:
Let's say I'm using the Northwind public OData service (https://services.odata.org/V2/Northwind/Northwind.svc/)
Due to network performance I want to query the Customers, Categories and Regions in one only request, like this:
URL: https://services.odata.org/V2/Northwind/Northwind.svc/$batch
--batch_8008-578f-c3c1
Content-Type: application/http
Content-Transfer-Encoding: binary
GET Customers HTTP/1.1
Accept: application/json
Accept-Language: en
DataServiceVersion: 2.0
MaxDataServiceVersion: 2.0
--batch_8008-578f-c3c1
Content-Type: application/http
Content-Transfer-Encoding: binary
GET Categories HTTP/1.1
Accept: application/json
Accept-Language: en
DataServiceVersion: 2.0
MaxDataServiceVersion: 2.0
--batch_8008-578f-c3c1
Content-Type: application/http
Content-Transfer-Encoding: binary
GET Regions HTTP/1.1
Accept: application/json
Accept-Language: en
DataServiceVersion: 2.0
MaxDataServiceVersion: 2.0
--batch_8008-578f-c3c1--
(I tested this in Postman, it works.)
I have other scenarios where this would be really useful, such as reading several individual entries at once, sending ChangeSets to change several entries in a "transaction", and calling function imports.
