Grpc vs rest7/9/2023 The protocol buffers describe the length of the components in the binary stream. GRPC on the other hand, utilizes HTTP/2 and protocol buffers, which can be simplified into binary over HTTP. Data is commonly in JSON format, which Java code deserializes into Java objects for usage within the application. Most servers will expose endpoints that expect specific headers and verbs and utilize the incoming data to perform operations. GET/POST/DELETE) to transmit messages from client to server. RESTful APIs use HTTP 1.0/1.1 and include usage of HTTP Verbs (ex. Although it is possible to convert the response into another format, it's uncommon and could affect performance. On the other hand, GraphQL defines its own query language that needs to be used when requesting data. So with that out of the way, here's my silly little Java-based gRPC vs Rest performance experiment.īefore we get into the experiment and testing, here's a quick overview. We can implement REST services to support one or multiple data formats like JSON and XML. Im really new to bazel and gRPC so I tried my. I then wanted to add gRPC-Gateway into the mix, as we will need to slowly transition into gRPC from an existing REST architecture. Following all the steps, I initialized the server and everything worked as expected. I've been that guy before, and it always helps to have relevant and concrete results to show everyone to help sway your point. I cloned grpc-kotlin to use their examples and chose to set up hellowworld example. This isn't an incredibly scientific experiment, but I feel like it at least provides somewhat clear results as to what one might expect when someone at your work starts pitching the new hotness (gRPC in this case) and swears that it will solve X or Y problem and have A or B performance benefits. So as a part of my continued learning, I developed this simple little test to see how the gRPC vs REST performance debate actually plays out within Java alone. However, while using Go I've come across gRPC usage more and more. I've since fallen in love with the language, though Java is still where I feel most at home. I'd heard plenty of good things about Golang, so I dove right in. However, a few months ago I was given the opportunity to jump into a greenfield Golang project at work. With that, I brushed the idea out of researching gRPC and continued with my standard workflows. I'd heard of some rumblings of a new RPC format a few years ago, and I immediately thought back to my days doing some light GWT (Google Web Toolkit) development. gRPC and REST Binary protocol: HTTP/2 uses binary, but not text format, therefore it is more compact and faster Multiplexing: HTTP/2 may send multiple. On most days I spend a majority of my time writing code that either make up or interact with RESTful endpoints, or downstream code triggered by an endpoint. As a Java Developer, RESTful APIs are my bread and butter.
