rsocket-fireandforget-example

An example of sending messages between applications with the fire-and-forget interaction model in RSocket.

In this example the count-client streams integers from 1 to 1000 to the count-service using the fire-and-forget interaction model.

Building the Example

Run the following command to build the example:

./gradlew clean build

Running the Example

Follow the steps below to run the example:

  1. Run the following command to start the count-service:

     ./gradlew :count-service:run
    
  2. In a new terminal, run the following command to start sending integers with the count-client:

     ./gradlew :count-client:run
    

    If successful, you will see that 1000 integers were sent in the client terminal:

     [main] INFO example.count.client.CountClient - Sending: 997
     [main] INFO example.count.client.CountClient - Sending: 998
     [main] INFO example.count.client.CountClient - Sending: 999
     [main] INFO example.count.client.CountClient - Sending: 1000
    

    and you will see that 1000 integers were received in the service terminal:

     [reactor-tcp-nio-3] INFO example.count.service.CountService - Received: 997
     [reactor-tcp-nio-3] INFO example.count.service.CountService - Received: 998
     [reactor-tcp-nio-3] INFO example.count.service.CountService - Received: 999
     [reactor-tcp-nio-3] INFO example.count.service.CountService - Received: 1000
    

    NOTE: You may not receive all 1000 messages on the service side. The fire-and-forget interaction model is not acked and is intended for situations where losing a few messages is acceptable.
