🔸GRPC: GRPC (gRPC Remote Procedure Call) is a high-performance, language-agnostic framework for building remote services. It uses Protocol Buffers (protobuf) as the interface definition language and binary serialization format. It uses HTTP/2 as its underlying protocol, which provides features like bidirectional streaming, header compression, multiplexing, and more. It's designed for high-performance, low- latency communication between clients and servers. 🔸Streaming is one of the core concepts of gRPC where several things can happen in a single request. This is made possible by the multiplexing capability of HTTP/2 . Server Streaming RPC: Where the client sends a single request and the server can send back multiple responses. For example, when a client sends a request for a homepage that has a list of multiple items, the server can send back responses separately, enabling the client to use lazy loading. Client Streaming RPC: Where the c
