Have added the required client, server, proto and proto generated files. The design of the example is as follows: 1. The client sends a bulk amount of data(approx. 2 KB in each iteration) to the server in a streaming call. 2. The server applies back-pressure by delaying reading of the requests, which makes the client pause sending requests after around 64KB 3. The client then resumes sending requests only after the server reads a few requests and clears the buffer. By adding print statements on data send/receive on both client and server side, the client pausing/resuming requests can be seen clearly. The client and server logs can be seen below: **Client Logs** ``` Request 10: Sent 20000 bytes in total Request 20: Sent 40000 bytes in total Request 30: Sent 60000 bytes in total Request 40: Sent 80000 bytes in total Received 10 responses Request 50: Sent 100000 bytes in total Received 20 responses Request 60: Sent 120000 bytes in total Received 30 responses Request 70: Sent 140000 bytes in total Received 40 responses Request 80: Sent 160000 bytes in total Received 50 responses Request 90: Sent 180000 bytes in total Received 60 responses Request 100: Sent 200000 bytes in total Received 70 responses Received 80 responses Received 90 responses Received 100 responses ``` **Server Logs** ``` Server started, listening on 50051 Request 10: Received 20000 bytes in total Request 10: Sent 20000 bytes in total Request 20: Received 40000 bytes in total Request 20: Sent 40000 bytes in total Request 30: Received 60000 bytes in total Request 30: Sent 60000 bytes in total Request 40: Received 80000 bytes in total Request 40: Sent 80000 bytes in total Request 50: Received 100000 bytes in total Request 50: Sent 100000 bytes in total Request 60: Received 120000 bytes in total Request 60: Sent 120000 bytes in total Request 70: Received 140000 bytes in total Request 70: Sent 140000 bytes in total Request 80: Received 160000 bytes in total Request 80: Sent 160000 bytes in total Request 90: Received 180000 bytes in total Request 90: Sent 180000 bytes in total Request 100: Received 200000 bytes in total Request 100: Sent 200000 bytes in total ```
