Unary RPC in FTP Service
Discuss what a unary remote procedure call (RPC) in gRPC is and learn how to implement it.
Unary RPC
In gRPC, a unary remote procedure call (RPC) is a type of RPC in which the client sends a single request to the server and waits for a single response. Unary RPCs are commonly used for simple client-server interactions, where the client needs to perform an operation and receive a response from the server. This type of RPC is based on the request/response model. It is straightforward and relatively easy to implement. gRPC offers flexibility in how the client and server interact during the execution of a unary RPC operation. Unary RPC can use both synchronous and asynchronous communication.
Synchronous communication
In synchronous communication, the client sends a request to the server and waits for the server to process the request and send back a response before continuing execution. When making a unary RPC call synchronously in gRPC, the client invokes the RPC method and blocks until it receives the response from the server. This blocking behavior means that the client thread is paused until the RPC operation completes, potentially leading to ...
