Performance: disable CPS-temporal notifications

To disable CPS-temporal notifications we need to have following properties configured as below :

Property	Description	Path from CPS root
NOTIFICATION_DATASPACE_FILTER_PATTERNS: NON-EXISTING-DATASPACE	Add / modify under services.cps-and-ncmp.environment section	docker-compose/docker-compose.yml
notification.enabled: 'true'	Add / modify under services.cps-and-ncmp.environment section. Make sure to always enable it as it is used by CPS for Async/Internal communications.	docker-compose/docker-compose.yml

docker-compose.yml view :

docker-compose (cps-and-ncmp)

cps-and-ncmp:
  container_name: cps-and-ncmp
  image: ${DOCKER_REPO:-nexus3.onap.org:10003}/onap/cps-and-ncmp:${CPS_VERSION:-latest}
  ports:
    - ${CPS_CORE_PORT:-8883}:8080
    - ${CPS_CORE_MANAGEMENT_PORT:-8887}:8081
  environment:
    notification.enabled: 'true'
    NOTIFICATION_DATASPACE_FILTER_PATTERNS: NON-EXISTING-DATASPACE

To verify if CPS-temporal notifications are disable :

Add consumer docker-compose service to "docker-compose/docker-compose.yml" as below :

kafka-consumer

  consumer:
    image: taion809/kafka-cli:latest
    container_name: kafka-consumer
    command: kafka-console-consumer.sh --bootstrap-server kafka:9092 --topic cps.data-updated-events
    links:
      - kafka

Open kafka-consumer "Logs" section as below :

If CPS-temporal notifications are disabled will see warning message as "WARN [Consumer clientId=consumer-1, groupId=console-consumer-32597] Error while fetching metadata with correlation id 9 : {cps.data-updated-events=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)"
