Enhancement - Use of protobuff instead of json serialization for server - server API calls

[saivishwak]

An enhancement request -

The protobuff protocol seems to be very efficient in serialization and deserialization than the JSON. So the use of this will have an improvement in bandwidth usage and faster API calls. It also has a schema to be defined which is good for non-typed languages like python and also the the serialized message can be deserialized in any language using Protobuff.
