Retry Example in gRPC Python

Prerequisite

  • grpcio >= 1.39.0
  • grpcio-tools >= 1.39.0

Running the example

In terminal 1, start the flaky server:

python3 flaky_server.py

In terminal 2, start the retry clients:

python3 retry_client.py
# Or
python3 async_retry_client.py

Expect results

The client RPC will succeed, even with server injecting multiple errors. Here is an example server log:

$ python3 flaky_server.py
