Question about timeouts

从 AWS Lambda C++ runtime 示例以及 issue 中展示的 run_handler 调用开始；复现 5 秒执行与 70 秒执行之间的差异。确定超时行为和配置记录在哪里，然后使相关的开发者参考足够清晰，以解释观察到的重启和配置选项。

Hello,

I have followed the examples here: https://aws.amazon.com/blogs/compute/introducing-the-c-lambda-runtime/

When I run my internal execution so that it takes 5 seconds everything works fine. But when I run it for 70 seconds I never get any response and the lambda function seems to be restarting several times. My guess is that is has to do with some timeouts. But how do I configure them? I cannot find any good developer reference.

static invocation_response my_handler(invocation_request const& req, Aws::S3::S3Client const& client) {
	using namespace Aws::Utils::Json;
	JsonValue json(req.payload);
	if (!json.WasParseSuccessful()) {
		return invocation_response::failure("Failed to parse input JSON", "InvalidJSON");
	}

	auto v = json.View();

	if (!v.ValueExists("s3bucket") || !v.ValueExists("s3key") || !v.GetObject("s3bucket").IsString() ||
		!v.GetObject("s3key").IsString()) {
		return invocation_response::failure("Missing input value s3bucket or s3key", "InvalidJSON");
	}

	auto bucket = v.GetString("s3bucket");
	auto key = v.GetString("s3key");

	AWS_LOGSTREAM_INFO(TAG, "Attempting to download file from s3://" << bucket << "/" << key);

	// Internal execution about 70 seconds...
       string response = "Success!";

	return invocation_response::success("We did it! Response: " + response, "application/json");
}

std::function<std::shared_ptr<Aws::Utils::Logging::LogSystemInterface>()> GetConsoleLoggerFactory() {
	return [] {
		return Aws::MakeShared<Aws::Utils::Logging::ConsoleLogSystem>(
			"console_logger", Aws::Utils::Logging::LogLevel::Info);
	};
}

Aws::Client::ClientConfiguration getS3Config() {

	Aws::Client::ClientConfiguration config;
	config.region = "us-east-1";
	config.scheme = Aws::Http::Scheme::HTTP;

	return config;
}

Aws::Client::ClientConfiguration getS3ConfigWithBundle() {

	cout << "USING S3 REGION: " << Aws::Environment::GetEnv("AWS_REGION") << endl;

	Aws::Client::ClientConfiguration config;
	config.region = Aws::Environment::GetEnv("AWS_REGION");
	config.scheme = Aws::Http::Scheme::HTTP;

	return config;
}

void run_lambda_handler() {

	Aws::S3::S3Client client(getS3ConfigWithBundle());
	auto handler_fn = [&client](aws::lambda_runtime::invocation_request const& req) {
		return my_handler(req, client);
	};
	run_handler(handler_fn);
}

int main(int argc, const char **argv) {
	Aws::SDKOptions options;
	options.loggingOptions.logLevel = Aws::Utils::Logging::LogLevel::Info;
	options.loggingOptions.logger_create_fn = GetConsoleLoggerFactory();
	Aws::InitAPI(options);

	run_lambda_handler();

	Aws::ShutdownAPI(options);

	return 0;
