We are planning to replace IBM MQ with Apache Kafka to implement pub-sub use-cases in future. Currently Mainframe(running Z/OS) applications are written using COBOL programming language & pushing messages to MQ. I went through the documentation to find out about Clients supported by Kafka and seems, it doesn't support COBOL.
What's the best approach to build producer on Mainframe and publish messages directly to Kafka topics with minimal change in existing applications ?
