The grpc Unary Server Interceptor opentelemetry-go-contrib/instrumentation/google.golang.org/grpc/otelgrpc/interceptor.go UnaryServerInterceptor returns a grpc.UnaryServerInterceptor suitable for use in a grpc.NewServer call that has unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent.
