I guess I should be more clear... batch means you can do things like combine these: GET /serviceRoot/Airports GET /serviceRoot/People into one request (and get the results in one response) I believe that's what the poster was asking. Here's a link to a different example from the OData site: https://www.odata.org/getting-started/advanced-tutorial/#batch https://www.odata.org/getting-started/advanced-tutorial/#bat... You're using the word "join". I'm not sure if you meant that in a relational sense or not. If yes, then maybe you're wondering if you can get airports with their related people, or people with their related airports in one request with OData. Again, the answer is yes.
