| # Deadline Example |
| |
| ## Overview |
| |
| This example shows you how to use deadline when calling calls. |
| |
| ### Try it! |
| |
| Once you have working gRPC, you can build this example using either bazel or cmake. |
| |
| Run the server, which will listen on port 50051: |
| |
| ```sh |
| $ ./server |
| ``` |
| |
| Run the client (in a different terminal): |
| |
| ```sh |
| $ ./client |
| ``` |
| |
| To simulate the test scenario, the test server implements following functionalities: |
| - Response Delay: The server intentionally delays its response for `delay` request messages to induce timeout conditions. |
| - Deadline Propagation: Upon receiving a request with the `[propagate me]` prefix, the server forwards it back to itself. |
| This simulates the propagation of deadlines within the system. |
| |
| If things go smoothly, you will see the client output: |
| |
| ``` |
| [Successful request] wanted = 0, got = 0 |
| [Exceeds deadline] wanted = 4, got = 4 |
| [Successful request with propagated deadline] wanted = 0, got = 0 |
| [Exceeds propagated deadline] wanted = 4, got = 4 |
| ``` |
