An R library for GRPC a high-performance, open-source universal RPC framework.
The following is copied from gRPC C++ - Building from source
sudo apt-get install build-essential autoconf libtool pkg-config
## If you plan to build from source and run tests, install the following as well:
sudo apt-get install libgflags-dev libgtest-dev
sudo apt-get install clang libc++-dev
git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc grpc_base
cd grpc_base
git submodule update --init
## In gcc 8.2 I got an error which I could fix with (see https://github.com/grpc/grpc/issues/17781)
## with the following two export lines. (uncomment and run if you gat an error when calling make).
#export CFLAGS='-g -O2 -w'
#export CXXFLAGS='-g -O2 -w'
make
sudo make install
sudo ldconfig
Easily create gRPC clients and servers from protobuf descriptions to build distributed services.

See install
for my installation notes...
There are runnable examples in the demo/
folder.
To start a HelloWorld server:
R -e 'demo("helloserver", "grpc")'
Or with much more detailed logging:
R -e 'library(futile.logger); flog.threshold(TRACE); demo("helloserver", "grpc")'
To run a client against a running HelloWorld server:
R -e 'demo("helloclient", "grpc")'
Both are cross compatible with the Node, Python and C++ Greeter examples provided by the grpc library.
This server implements the above service along with the standard GRPC Health Checking Protocol:
R -e 'demo("health-check-server", "grpc")'
The client runs a health-check then calls the Hello, World! method once:
R -e 'demo("health-check-client", "grpc")'
Please check the sources of the server to see how to bundle services defined in multiple proto
files.
There's a simple trained on the iris
dataset and making that available for scoring via a gRPC service:
R -e 'demo("iris-server", "grpc")'
An example client to this service from R:
R -e 'demo("iris-client", "grpc")'
