gRPC, a high-performance RPC framework, utilizes HTTP/2’s capabilities to enhance communication between services. It leverages HTTP/2’s binary framing and multiplexing abilities for efficient data transfer. Binary framing reduces overhead by enabling smaller payloads while multiplexing allows concurrent exchanges on the same connection, reducing latency.
HTTP/2 headers compression via HPACK minimizes bandwidth usage, improving performance. gRPC also benefits from HTTP/2’s flow control mechanism ensuring optimal use of network resources. Stream prioritization is another feature used by gRPC, allowing important streams to be sent first.
Moreover, gRPC uses HTTP/2’s server push functionality for bi-directional streaming. This enables both client and server to send data independently without waiting for the other party to request it, facilitating real-time communication.
