The implementation of Golang GRPC provides high performance and is an open source.stream.CloseAndRecv- it is used for closing the stream and waiting for the response from the server.stream.Send- it is used for sending the packet to the stream.Here in this example, the split function is used for creating the chunks in the body. For some cases where you only need to provide the name of the go package where the file belongs, use the command given below: The name of the package can also be used for preventing collision and various options to generate the code. It can also generate the code required for manipulating the data structure since it is language-agnostic.īy creating a file notes.proto in the notes folder, the file gives information about which version of the protocol buffer is being used. The file is simple to write and provides a high-level definition of what the application is doing at the backend. The declarative file “.proto” is used for describing the data structures which is a message and the interface of the application which is services. The separation of the code logic from that of business requirement is considered a good practice and for this example, we will be creating a notes folder for the business logic of your application.Īlong with providing a fast and efficient way of data format, the protocol buffer also comes with the tools and the ecosystem, for making the development of applications easier. In order to understand this better, let's take an example.Ĭreating Golang Project with gRPC Implementation of Application Logic It is important if we want to change the format of the message without introducing downtime to it. The protocol buffer, also known as protobuf is a language that is platform neutral and is used for structuring the data with fast built-in serialization and support for schema migration. By using a protocol buffer, we can encode the semantics of the message in a form that is parseable and which can be shared between the client and the server. The protobuf is also known as protocol buffer and is mainly used with Golang GRPC. Due to this binary format, the size of these messages are smaller and the combination of these smaller messages leads to faster communication that offers strong performance when compared to REST-based APIs. They provide a representation of binary data which is more efficient as compared to any other text-based formats such as XML or JSON. In Golang GRPC, the key element is the protocol buffer. The persistent connection of TCP for multiple sequential requests and responses for a single connection of TCP.Sending multiple requests by using multiplexing and then receiving multiple responses simultaneously over a TCP connection which is one-sided.Compression of the header to reduce the size of the message.The protocol that Golang GRPC uses is HTTP/2 which has various ways for improving the performance: The difference between Golang GRPC and REST API means that the REST API can’t be translated easily into the Golang GRPC but instead it needs to be updated according to the different protocol. REST, on the other hand, is a resource-based protocol that is mainly used for informing the server that the client needs resources that are to be created, updated, read or delete depending upon the request of the body. For intensive and effective/efficient communication, the Golang GRPC is preferred because it supports streaming of both the client and the server streaming side. Due to this, the Golang GRPC is known for the type of inter-process communication protocol which is known as IPC protocol, and is built by using Protobufs which is mainly used for handling the messages or communication between the client and the server side. The Golang GRPC is also known as the Remote Procedure Call framework based on the action paradigm and is very similar to calling a function remotely from other microservices in gRPC. The Golang GRPC package implements an RPC system which is called gRPC. This framework is a general RPC framework that gives first preference to HTTP/2 and mobile. The implementation of the Golang GRPC provides high performance and is an open source.
