Comment

Rate Limiter Pattern might sound same as Circuit Breaker in some cases. However there is an important difference!

Rate Limiter helps to protect the server from over loading by controlling throughput.

Circuit Breaker helps to keep the client safe and functional when the target server is failing / unresponsive.

@RestController
public class ComputeController {

    @GetMapping("/double/{input}")
    public ComputeResponse doubleValue(@PathVariable int input){
        return ComputeResponse.of(input, 2*input, ResponseType.SUCCESS, Strings.EMPTY);
    }

    @GetMapping("/square/{input}")
    @RateLimiter(name = "squareLimit", fallbackMethod = "squareErrorResponse")
    public ComputeResponse getValue(@PathVariable int input){
        return ComputeResponse.of(input, input * input, ResponseType.SUCCESS, Strings.EMPTY);
    }

    public ComputeResponse squareErrorResponse(int input, Throwable throwable){
        return ComputeResponse.of(input, -1, ResponseType.FAILURE, throwable.getMessage());
    }

}
