gRPC

aid: grpc
name: gRPC
description: gRPC is a high-performance, open-source universal RPC framework that uses HTTP/2 for transport, Protocol Buffers
  as the interface description language, and provides features such as authentication, bidirectional streaming and flow control,
  blocking or nonblocking bindings, and cancellation and timeouts. Originally developed at Google, it is now a CNCF project.

  description: The gRPC core framework defines the RPC protocol, service definition format using Protocol Buffers, and the
    fundamental call lifecycle including unary, server-streaming, client-streaming, and bidirectional streaming patterns over
    HTTP/2. It is the foundational specification implemented by all language-specific gRPC SDKs.

  name: gRPC Health Checking Service
  description: The gRPC Health Checking Protocol defines a standard service that gRPC servers implement to expose health status
    information to clients and load balancers. Servers implement the Health service proto to report per-service readiness,
    and clients can configure automatic health-check-based connection management.

  name: gRPC Server Reflection
  description: The gRPC Server Reflection Protocol allows gRPC servers to declare the protobuf-defined APIs they export over
    a standardized RPC service, including all types referenced by request and response messages. This enables command-line
    debugging tools and clients to dynamically discover and invoke gRPC services without pre-compiled stubs.
