PAS 22.1.2 The Designer allows to write synchronous messages to an Apache Kafka event topic. The access to Kafka can be configured statically by an alias - dynamic access is not available. The Kafka Producer supports SSL but no Kerberos authentication.
To use the Apache Kafka Producer adapter, you need basic knowledge of Apache Kafka. Refer to the Apache Kafka Documentation for any deeper insights.
