grpc vs rest performance

Benchmark for .NET Core 3.1. Here’s an example of a minimal Go function that makes a POST request using a struct as input and another struct for output using the built-in HTTP and JSON libraries: Here’s trying to achieve the same thing using gRPC and Protocol Buffers: As you can see, consuming gRPC endpoints is definitely less code than consuming REST endpoints (especially since you only need to perform the dial once). Both servers are fairly simple, implementing the ADT required by the client. gRPC is a lightweight and quick system for requesting data, it’s a fresh take on an old method called Remote Procedure Call or RPC. According to official blog “GRPC is a open source high performance RPC framework that can run in any environment, it can efficiently connect services across data … Nonetheless, REST is not going anywhere anytime soon. This document explains how to get the best performance possible from gRPC. In GraphQL on the other hand, you’d simply send a single query to the GraphQL server that … Nonetheless, REST is not going anywhere anytime soon. Companies everywhere are realizing the benefits of building a microservice-based architecture. /0, /1, and /2 with a single string payload. Our main goal here is to come up with an application – with 2 different implementations (REST and gRPC) for the exact same functionality. Evaluating Performance of REST vs. gRPC. We decided that provided support and documentation for Protocol Buffers in a particular language is strong, we should be able to overcome the debugging problems using language-based debugging tools, and in turn, benefit from the faster development time of gRPC. Starts the ASP.NET MVC Core REST API. I have … The key benefit of HTTP/1.1 is a wider adoption by the general public. Tagged with grpc, rest, dotnet, dotnetcore. perform only a single TCP handshake for the entirely of a test. If you are new to gRPC, please take a look at these gRPC related articles first. HTTP/2 natively supports request multiplexing [5], which allows for an unbounded amount of requests to be made and responded to concurrently and asynchronously. gRPC vs REST. Using gRPC and Protocol Buffers, where language-native objects are provided for clients, many errors related to dealing with the API are caught by the compiler [9], which is significantly more convenient than looking at error codes of a REST API. Streaming was slightly worse than calling REST. Ideally, all of our services could support HTTP/2 and fallback onto HTTP/1.1 for pre-existing services not yet upgraded.

GRPC Vs REST; Creating GRPC Service; Creating GRPC Client; WCF to GRPC; Conclusion; What is gRPC . These interfaces come with language-native objects to use to pass into and accept from them.
