Asynchronous Publishing

This connector does not support asynchronous publishing. Publish acknowledgments are resolved synchronously for all workflows regardless of the configuration option that you set: 

<workflow-id> : The workflow ID ([0-19])
solace.connector.workflows.<workflow-id>.acknowledgment.publish-async=(true|false)

Enabling publish-async will enable asynchronous publishing on the connector’s core but the effective publishing mode is still synchronous due to a lack of support on either the consumer binding or the producer binding.
