External publication protocols

Support is provided for the following variants of Kafka integration:

• Direct by Kafka producer node
• MQ Proxy

The reasons to support the MQ Proxy are:

• To provide transactional isolation.
• To isolate the EPF from potential delays during communication with a remote Kafka server.

The following two new publication URLs are supported:

• Kafka://<topic>
• KafkaMQ://<queue>/<topic>

The variables in the format of the publication URLs are shown in the following list.

<topic>

Is the Kafka topic that events are published to.

<queue>

Is the intermediate proxy queue.
