We have a view table which is a join of 7-8 source tables. This table has 10 child tables.
I would like to know if the time taken to generate odata get response would be decreased if i remove the parent child relationships.(parent table odata response would not have any urls of its child tables.)
If you are just querying the view through the OData layer with out $expand, or "atom" format or json with "full-metadata", the child tables are not going to be in the payload. So, I do not think it will affect that much if you remove the relationships.
