gRPC

The gRPC component can be used to create a gRPC server. To enable observability, it injects unary and stream interceptors.

As the server implements the Patron component interface, it also handles graceful shutdown via the passed context.

Setting up a gRPC component is done via the Builder (which follows the builder pattern), and supports various configuration values in the form of the grpc.ServerOption struct during setup.

Check out the examples/ folder for a hands-on tutorial on setting up a server and working with gRPC in Patron.

Metrics

The following metrics are automatically provided when using WithTrace():

• component_grpc_handled_total
• component_grpc_handled_seconds

Example of the associated labels: grpc_code="OK", grpc_method="CreateMyEvent", grpc_service="myservice.Service", grpc_type="unary".
