Restlight

Restlight is a lightweight and rest-oriented web framework.

Quick Start

Create a Spring Boot application and add dependency

<dependency>
    <groupId>io.esastack</groupId>
    <artifactId>restlight-starter</artifactId>
    <version>${mvn.version}</version>
</dependency>

Write your Controller

@RestController
@SpringBootApplication
public class RestlightDemoApplication {

    @GetMapping("/hello")
    public String hello() {
        return "Hello Restlight!";
    }

    public static void main(String[] args) {
        SpringApplication.run(RestlightDemoApplication.class, args);
    }
}

Run your application and then you would see something like

Started Restlight server in 1265 millis on 0.0.0.0:8080

curl http://localhost:8080/hello

Performance

Test cases

• We built an echo server by ESA Restlight and used a http client to do the requests for RPS testing with different bytes of payload(16B, 128B, 512B, 1KB, 4KB, 10KB) and different Threading-Models(IO, BIZ).
• Also we used spring-boot-starter-web(2.3.2.RELEASE) to build a server which is same with above for RPS testing.

Hardware Used

We used the following software for the testing:

• wrk4.1.0

• 	OS	CPU	Mem(G)
  server	centos:6.9-1.2.5(docker)	4	8
  client	centos:7.6-1.3.0(docker)	16	3
