What it does
The Kafka adapter of Cloud Integration, a part of SAP Integration Suite, connects to an external Kafka broker over the Kafka protocol, and its sender side receives messages from the broker into an integration flow. SAP's page points to SAP Note 3715816 for the adapter's feature scope, which was not read.
Remaining work
An integration flow that takes each record from the Kafka sender adapter and hands it to the application, and an endpoint or a broker subscription in the application for it to arrive at. Neither is part of the adapter.
