msk-pipeline: 
  supply: 
    kafka: 
      acknowledgments: true                  
      matters: 
         - title: "ev-device-topic " 
           group_id: "opensearch-consumer" 
           serde_format: json                 
      aws: 
        # Present the Function ARN with entry to MSK. This function ought to have a belief relationship with osis-pipelines.amazonaws.com 
        sts_role_arn: "arn:aws:iam:: ::<<account-id>>:function/opensearch-pipeline-Function"
        # Present the area of the area. 
        area: "<<area>>" 
        msk: 
          # Present the MSK ARN.  
          arn: "arn:aws:kafka:<<area>>:<<account-id>>:cluster/<<title>>/<<id>>"
