Known Issues

  • The Anypoint MQ connector currently doesn’t support tracking.

    Example with tracking:

    <flow name="customers-all-get" tracking:enable-default-events="true">
      <anypoint-mq:subscriber config-ref="Anypoint_MQ_Configuration" destination="testQueue" acknowledgementMode="AUTO"/>
      <tracking:transaction id="customers-all-get"/>

    This is the same example with the subscriber tracking statement removed:

    <flow name="customers-all-get">
      <anypoint-mq:subscriber config-ref="Anypoint_MQ_Configuration" destination="testQueue" acknowledgementMode="AUTO"/>
