Hi @sbalakrishn! I don't think there's any built-in function that allows you to do this without some manual work. See open-policy-agent/opa#1143 for an open issue on this.

I guess I would do something like traverse each object using the walk built-in function, and compare it to the corresponding node of the other object.. but could be tricky to report it back in a nice format. If you have an example of two objects to compare, we could give it a shot :)
