Hi, I am using Cloudflare Workers to access dgraph cloud. What’s the best most performant way to do that? Should I use gRPC JS Client, HTTP JS Client, or cURL http API? Of course every option of these 3 work fine, but I ask in terms of optimization, which of these 3 will give me the best results. I think it will be gRPC because it’s faster due it operating on the binary level, but are there really no drawbacks? thanks a lot ---

The advantage of grpc is using protobufs which will help with decoding times on larger messages, but since all the endpoints are unary, there is not a big difference in operation. I would say, do whatever feels right in your code. Probably not the raw http API as it will be harder to maintain in case of changes.
