Spring cloud stream artemis binder concurrency not working

Question

I have set up a spring cloud stream with an Artemis binder https://github.com/snowdrop/spring-cloud-stream-binder-artemis . I have two applications ie a producer as well as a consumer. Below is my application.yml configuration

Producer config

spring:
  main:
    allow-bean-definition-overriding: true
  cloud:
    stream:
      poller:
        fixed-delay: 5000
      bindings:
        sourceForBroker-out-0:
          destination: exchange
      function:
        definition: sourceForBroker

Consumer Config

spring:
  main:
    allow-bean-definition-overriding: true
  cloud:
    stream:
      bindings:
        r1:
          destination: exchange
          group: group1
          consumer:
            max-attempts: 1
            concurrency: 10
      function:
        bindings:
          r1Consumer-in-0: r1
        definition: r1Consumer

Everything working fine ie producer sent data to the queue and the consumer is able to process data but concurrency is not reflected. when I check the Artemis console I see there is only one consumer. Attached console screenshot

Answer 1

One producer can have many consumer. Your consumer is one only that's why it is showing one thread only.
