Asynchronous Publishing
Asynchronous publishing allows the connector to process new messages without the need to wait for the previous message’s publish acknowledgment. While this can boost performance, it does come with a trade-off, as it may increase the chances and volume of duplicate messages.
A workflow can be configured to wait for the publisher's acknowledgments, asynchronously with the following configuration options:
# <workflow-id> : The workflow ID ([0-19]) solace.connector.workflows.<workflow-id>.acknowledgment.publish-async solace.connector.workflows.<workflow-id>.acknowledgment.back-pressure-threshold solace.connector.workflows.<workflow-id>.acknowledgment.publish-timeout
In general, reducing the publish-timeout
option increases the probability of duplicate message deliveries, while increasing the back-pressure-threshold
option is likely to result in a higher occurrence of duplicate messages.
