Spring RSocket Protobuf

Example project for Spring Boot RSocket with Protocol Buffer

Example Feature.

• RSocket client-server.

• Endpoint /api/person → json endpoint with simple pojo.

• Endpoint /api/proto-json/person → protobuf object as a json endpoint(Not working).

• Endpoint /api/proto/person → protobuf object endpoint.

• Endpoint /api/rsoc/person → rsocket client-server endpoint with protobuf mime type.

• Ports

  • person service → 8080

  • person service rsocket → 9080

  • person client service → 8081

  • person client service rsocket → 9081

• Performance of the varies endpoint/communication modes can be compared using actuator endpoint /actuator/prometheus of person-client-service

How to test rsocket directly.

• Download rsc.jar, a rsocket cli client.

• Now execute below command to retrieve json data.

  java -jar rsc-0.4.2.jar tcp://localhost:9080 \
      -r io.github.kprasad99.json.person \
      --stream

Compare the performance of endpoints.

Though the data is too less you can add the data to database before running the applicaiton.

• Start the applications, prometheus and grafana.

  $ docker-compose -f docker-compose-dev.yml up -d

  Note	openjdk docker image is a custom image, you might need to change to any available jdk-11 one.

• Once the application is started open Grafana UI at http://localhost:30072

  Note	Default username/password is admin/admin

• Open postman and import collection postman/spring-rsocket-protobuf.postman_collection.json.

• Now use the runner tool to run the collection with N-number of requests.
